Delivering fast boot times in Windows 8

[アーティクル]
09/08/2011

When it comes to talking about "fundamentals" we want to start with boot time – no feature gets talked about and measured more. We designed Windows 8 so that you shouldn't have to boot all that often (and we are always going to work on reducing the number of required restarts due to patching running code). But when you do boot we want it to be as fast as possible. This is a very deep topic and we have a lot of folks focused on it. We made a bigger leap in this area with Windows 8 than we have in a long time due in no small part to cooperation across the whole ecosystem. Gabe Aul, a director of program management in Windows, authored this post (a first in what will be a series of posts on fundamentals).
--Steven

Few operations in Windows are as scrutinized, measured, and picked apart as boot. This is understandable—boot times represent an effective proxy for overall system performance and we all know the boot experience is an incredibly important thing for us to get right for customers. Data shows that 57% of desktop PC users and 45% of laptop users shut down their machines rather than putting them to sleep. Overall, half of all of users shut down their machines rather than putting them to sleep.

Qualitatively, people say they prefer to shut down because they want to have their PC completely “off” so that it uses no power – either to preserve battery life or to reduce their energy use. Hibernate is also a good option for this since it similarly has no power draw, and many people really like it. However, it’s clearly not for everyone, since one of the other things we’ve heard is that many people want to turn their PCs on and have it be a “fresh start” rather than running all of the stuff from their previous session. Sleep/resume is the best option for fast on/off transitions on today’s PCs, but it still consumes some power in order to preserve the contents of RAM, which means battery drain – even if it’s only a little bit on a well optimized system. All of this is happening with the backdrop of how we all use our mobile phones today, which is almost never restarting them, and always using what feels closest to a sleep-like state.

Our challenge then, was to design a way to meet all of these desires on today’s PCs without requiring some special new hardware. These were our goals:

Effectively zero watt power draw when off
A fresh session after boot
Very fast times between pressing the power button and being able to use the PC.

In Windows 7 we made many improvements to the boot path, including parallel initialization of device drivers, and trigger-start services, but it was clear we’d have to get even more creative (and less incremental) if we hoped to get boot performance anywhere close to fast enough to meet all of these needs.

Our solution is a new fast startup mode which is a hybrid of traditional cold boot and resuming from hibernate.

Before I go into exactly how it works though, a little background is probably helpful on how shutdown and boot works today in Windows 7.

Shutdown entails:

The user initiates a shutdown by selecting “shut down” from the Start menu, or by pressing the power button; or an application initiates shutdown by calling an API such as ExitWindowsEx() or InitiateShutdown().
Windows broadcasts messages to running applications, giving them a chance to save data and settings. Applications can also request a little extra time to finish what they’re doing.
Windows closes the user sessions for each logged on user.
Windows sends messages to services notifying them that a shutdown has begun, and subsequently shuts them down. It shuts down ordered services that have a dependency serially, and the rest in parallel. If a service doesn’t respond, it is shut down forcefully.
Windows broadcasts messages to devices, signaling them to shut down.
Windows closes the system session (also known as “session 0”).
Windows flushes any pending data to the system drive to ensure it is saved completely.
Windows sends a signal via the ACPI interface to the system to power down the PC.

And boot entails:

After pressing the power button, the PC’s firmware initiates a Power-On Self Test (POST) and loads firmware settings. This pre-boot process ends when a valid system disk is detected.
irmware reads the master boot record (MBR), and then starts Bootmgr.exe. Bootmgr.exe finds and starts the Windows loader (Winload.exe) on the Windows boot partition.
Essential drivers required to start the Windows kernel are loaded and the kernel starts to run, loading into memory the system registry hive and additional drivers that are marked as BOOT_START.
The kernel passes control to the session manager process (Smss.exe) which initializes the system session, and loads and starts the devices and drivers that are not marked BOOT_START.
Winlogon.exe starts, the user logon screen appears, the service control manager starts services, and any Group Policy scripts are run. When the user logs in, Windows creates a session for that user.
Explorer.exe starts, the system creates the desktop window manager (DWM) process, which initializes the desktop and displays it.

There are a lot more specific details here, if anyone wants to go deeper: https://msdn.microsoft.com/en-us/windows/hardware/gg463386

The key thing to remember though is that in a traditional shutdown, we close all of the user sessions, and in the kernel session we close services and devices to prepare for a complete shutdown.

Now here’s the key difference for Windows 8: as in Windows 7, we close the user sessions, but instead of closing the kernel session, we hibernate it. Compared to a full hibernate, which includes a lot of memory pages in use by apps, session 0 hibernation data is much smaller, which takes substantially less time to write to disk. If you’re not familiar with hibernation, we’re effectively saving the system state and memory contents to a file on disk (hiberfil.sys) and then reading that back in on resume and restoring contents back to memory. Using this technique with boot gives us a significant advantage for boot times, since reading the hiberfile in and reinitializing drivers is much faster on most systems (30-70% faster on most systems we’ve tested).

Sample of test results from System Integration Test lab systems.
Click to see a bigger version of this chart.

It’s faster because resuming the hibernated system session is comparatively less work than doing a full system initialization, but it’s also faster because we added a new multi-phase resume capability, which is able to use all of the cores in a multi-core system in parallel, to split the work of reading from the hiberfile and decompressing the contents. For those of you who prefer hibernating, this also results in faster resumes from hibernate as well.

Representation of different phases between cold boot and fast startup.
Click to see a bigger version of this chart.

It’s probably worth mentioning quickly how we treat the hiberfile—if you read this and immediately went and did a dir /s /ah hiberfile.sys you would have found that it’s a pretty big file on disk. The hiberfile is sized by default at 75% of physical RAM. The file is essentially a reservation for hibernation data that will be written out as the system is dropping into hibernation. Typically much less space is actually used, and in the case of our fast startup usage, it’s typically ~10-15% of physical RAM but varies based on drivers, services, and other factors. The system also treats the hiberfile slightly differently than other files on disk, for example, the Volume Snapshot service ignores it (a small performance benefit.) You can disable hibernation and reclaim this space by running powercfg /hibernate off from an elevated command prompt. But be aware that if you do this, it will disable hibernation completely, including some nice capabilities like fast startup as well as hybrid sleep, which allows desktop systems to do both a sleep and hibernate simultaneously so if a power loss occurs you can still resume from the hibernated state. You can also run powercfg /hibernate /size and specify a value between 0 and 100 for the percentage of physical RAM to reserve for the hiberfile – but be careful! Specifying too small a size can cause hibernation to fail. In general, I recommend leaving it enabled at the default value unless you’re working on a system with extremely limited disk space.

Another important thing to note about Windows 8’s fast startup mode is that, while we don’t do a full “Plug & Play” enumeration of all drivers, we still do initialize drivers in this mode. Those of you who like to cold boot in order to “freshen up” drivers and devices will be glad to know that is still effective in this new mode, even if not an identical process to a cold boot.

This new fast startup mode will yield benefits on almost all systems, whether they have a spinning HDD or a solid state drive (SSD), but for newer systems with fast SSDs it is downright amazing. Check out the video below to see for yourself:

Your browser doesn't support HTML5 video.

Download this video to view it in your favorite media player:
High quality MP4 | Lower quality MP4

One thing you’ll notice in the video was how fast the POST handoff to Windows occurred. Systems that are built using Unified Extensible Firmware Interface (UEFI) are more likely to achieve very fast pre-boot times when compared to those with traditional BIOS. This isn’t because UEFI is inherently faster, but because UEFI writers starting from scratch are more able to optimize their implementation rather than building upon a BIOS implementation that may be many years old. The good news is that most system and motherboard manufacturers have begun to implement UEFI, so these kinds of fast startup times will be more prevalent for new systems.

Of course, there are times where you may want to perform a complete shutdown – for example, if you’re opening the system to add or change some hardware. We have an option in the UI to revert back to the Windows 7 shutdown/cold boot behavior, or since that’s likely a fairly infrequent thing, you can use the new /full switch on shutdown.exe. From a cmd prompt, run: shutdown /s /full / t 0 to invoke an immediate full shutdown. Also, choosing Restart from the UI will do a full shutdown, followed by a cold boot.

Boot work is mostly owned by our Kernel Platform Group, but a number of teams came together in Windows 8 to make changes across the OS to support this new mode, plus other exciting boot changes that we’ll talk about very soon. We’re really enjoying the boot performance of Windows 8 in our internal use, and are looking forward to you being able to try it for yourselves so you can let us know what you think.

Are you using this on average hardware? Or optimized? That will make the difference for me. If it can start up that fast even on average PC from staples then I'm impressed. If it's like one of the better models with better hardware then this isn't exactly anything to be excited about. What would be nice if windows 7 could be that fast. A good thing is if you can make windows 8 eat up less resources than windows 7 or give us a service pack that makes windows 7 lighter and windows 7 boot faster.

:O Holy! If she didn't have the laptop battery removed, I wouldn't have believed her! That is AMAZING! Great job guys! Quick question: In the past, the boot performance of Windows PCs have degraded over time as applications are installed/removed and the registry is mucked up. Is this new boot method still vulnerable to this type of degradation? Will it still boot just as fast 5 years down the road? Have you done any lab simulations regarding this scenario? Keep up the great work!

Well, that was a bit unexpected (especially at this time of day, usually posts come earlier). I do have a questions, however. Earlier Steven noted that the classic Windows experience isn't loaded at bootup. In light of that, I was wondering exactly how much of what we see in the video is due to booting into the Immersive environment versus hybrid booting and other boot improvements. Is there any way to get a 1-to-1 comparison booting Windows 8 to the classic desktop? Thanks

One of the main concerns for businesses is how to minimize power consumption since they have to have ALL computers on 24/7 for maintenence and updates sake. How will Win8 and Windows Server 8 be able to ensure that all Win8 PCs can remain in hibernate/standaby mode to drastically reduce power usage and be woken up for maintenence/updates and when anything needs to be pushed to them from the server?

I must add that all Windows versions are getting slower the longer they have been on a computer. Guess Microsoft had some hidden info on their site about that to some years ago after XP was released. It stated that XP needed to be reinstalled every 6th month. Vista and 7 are getting like chewing gum after 6 months..... XP don't need to be reinstalled that often, but both Vista and 7 have to. What does that tell us. Yes, exactly ! XP still rocks the socks off Vista and 7. Therefore 8 will be the same.

Very impressive (shame we didn't get to see how long it then takes to load the full Windows "desktop". Being in IT I've noticed the Win 7 boots up faster than XP, but the shutdown often takes a very long time (not good if staff are in a hurry to get to a meeting or catch a train, etc). If Windows Updates have been approved, you literally have to wait around for 5-10 minutes (and as a result have had some staff members ignore the message and forced their laptop to turn off). Have you been working on improvements to this area as well?

Are you guys going to make it the tiles a bit more interesting? They just look like boring flat squares at this point. Windows 7 needs an update so that it doesn't slow down in performance with time same with vista. Also it would be nice to not be as much of a resource hog.

Some devices didn't worked properly after sleep resume in Windows Vista/7. Also there are a lot of resume of sleep triggers. Of course you can turn them off in 7. But it would be nice if you could select which ones to be ignored exactly. For example, I want my PC to turn itself on so Media Center records something from TV, but I don't want to get up in the middle of the night to investigate why the heck it resumes from sleep without any obvious reason... I hope you considered that in Windows 8. :)

For the shutdown command, I think /s should behave same as previous versions, means a normal (full) shutdown. If someone relied on a shutdown script works in previous version of windows in order to replace some hardware, the new shutdown command apparently will cause serious problem. Instead of /full, a /fast option means the new fast shutdown machenism should be added.

Wow. Seriously, wow. If you look in the video at the amount of time it takes after POST, it's about 2 seconds to the login (CTRL + ALT + DEL) screen, and less than 2 seconds more to the "desktop" screen. The longest part of the boot for this machine is something over which Microsoft has no direct control. Very impressive!! One thing I'm hoping you'll talk more about is the equivalent of Standby time for laptops/slates. The typical behavior seems to be something like this: Sleep Mode is favored for fast resume, and Hibernation is only triggered if the battery is nearly depleted (unless invoked manually--something most users typically just don't understand or do... they get confused when presented a bunch of different "shut down" options). That works pretty well, except that Sleep Mode typically still draws a surprising amount of power (significantly more than the competition). For what it's worth, on a Samsung 9 Series laptop, the cold boot times are actually noticeably faster than resuming from hibernation. Are there any improvements here as well? It'd be great to see a fast resume mode (like Sleep Mode) where you can pull out your laptop several hours or a day later, be up in a couple seconds, and not have lost 30-40% of battery. Also, perhaps reboots to clear out the errant application, reset memory utilization, and otherwise "freshen up" the system will be less necessary with Win8, but if not, it is unfortunate that this scenario is not helped much by the improvements here. That scenario is also not reflected in the graphs in this article. As someone else mentioned as well, shutdown times are not covered here, and those can sometimes be quite long when you are in a hurry. The boot time work is excellent. Keep it up!! Very excited for Build. :)

Wow, pretty impressive. But i have to say, if people still shut down windows instead of hibernating/sleeping it's a user education or interface problem, not a call to make oldschool boot faster. Rebooting isn't necessary, teach people that and make it harder to find the shut down button, or less inviting. iPad and Macbook air for example brags about "instant startup" which is actually just sleep-mode. If you actually shut down an iPad it takes 30sec+ to boot it up again. Windows can behave exactly the same with sleep-mode. Rename hibernate to something more meaningful like "Pause windows and shut down computer" and sleep to "Put computer in quick resume standby". Hibernate vs Sleep is very confusing, the Swedish translations of it (Viloläge vs Vänteläge) are even worse, a more correct translation to english of their meaning is "Rest mode" and "Wait mode" - totally subtle difference. Might be the same for other languages too. Just giving you some hints that such an important difference for such a misunderstood feature shouldn't simply be "explained" by one word.

Will all GDI resources be freed/reset when using the new boot? The shared and limited GDI resource space is still a problem in Windows 7. I've seen required reboots because no more GDI handles were available and display issues occurred after running Windows for some days and using programs with GDI resource leaks (the Start menu no longer displayed correctly, for example).

Sure, that looks nice for laptop users. I'd like to see some desktop user love too. The only time I turn my computers off is when I have to install drivers or feel like installing updates. I'd want to be able to do this without losing my user session. It's such a chore to re-open all the programs and files, and there's bound to be lost state in some of them, that I only install updates maybe once every 3 months or so, because a reboot is so disruptive. Moving more drivers to userspace helped a bit. And don't even get me started on installing updates on servers...

@Steven Sinofsky Steven, I'd like to know whether the Windows team is aware of performance degradation after Windows being used over a long/certain period of time, and this including the boot times as well. I mean I often saw this kind of explanations where the PCs circumstance/condition being used, such used in the "Win8 vs Win7 comparison" figure above, are actually NEWLY FRESH-INSTALLED Windows PCs where not much apps/drivers installed, have not been used for a long period of time, and importantly not reflect a real world PC usage scenario where a PC has been used a long period of time and a lot of apps/drivers installation/uninstallation involved. While the figure above itself represents a fact and a truly remarkable achievement, but I think it could also mislead people in some way or another. In a full spectrum period of time of a PC usage, I see at least two periods of time. The first period represents a newly fresh-installed Windows situation where one just installed it, including initial fundamental drivers and apps. Usually, people immediately notice how fast it could be, and of course be happy because of it :). But, this period only takes duration about 10% of the full spectrum. The second period, where this takes 90% of it, represents a situation where Windows has been used for long/certain period of time and a lot of apps/drivers installation/uninstallation, or even Windows reconfiguration, etc. Thus, improving Windows boot times in the first period is critical and excellent. But, is there any consideration also taken for the second period? I've personally used Win7 for more than 1 year and noticed that Windows performance has degraded over time, including the boot times. After I cleanly installed it, I notice it being snappier again. But the question is should I periodically perform a clean Windows installation just to experience an pleasant and acceptable Windows experience in term of performance? Well, I don't want to if I don't have to :). Also I've heard a lot of people complaining about Windows performance degradation over time. And I think that has already become a serious issue in Windows. So, what do you think about these all? Do I assume correctly about the Windows testing environment being used in the development? Is there any metric being used in Windows SQM? The best I can notice is Diagnostics-Performance in Event Viewer, but I'm not sure about how Windows team use it to tackle this Windows performance degradation over time issue. Thanks. P.S.: Sorry if I don't use technically correct terms above, but I hope you get the idea.

a feature that would be useful for me is the ability to automatically log in on boot. currently it's a two step process with a wait after each step but for those PCs that are used mostly by one user it would be very helpful. i could turn it on and go make some tea knowing when i come back my desktop is ready. i know there are a number of security considerations, but auto login to a locked screen should help.

This is great news. Boot speed is important. Actually, if it's a single-user PC, why not have an option to load a session for the user in the background before they've logged on (i.e. log them on in the background but then, for security reasons, lock their session, prompting them for a password for security reasons)? That way, someone who turns on their computer and then goes to make a cup of coffee (which will hopefully be less necessary if booting becomes fast some day) won't still have to wait another 20 seconds after entering their password. Any plans to correct Windows' broken Backup messages? (I have a problem similar to this one: answers.microsoft.com/.../5bc27efe-9aaa-455c-996e-ff24c8931e85 ). Windows 7's "Programs & Features" is better than XP's "Add/Remove Program Files". I only have to wait 20 seconds for the list of programs to load, instead of a minute. But uninstalling things still takes too long.

You have a typo on point 2 of what the boot entails. You say irmware instead of Firmware. Can't believe no-one else has mentioned it. Do I win a prize! Otherwise, nice job on the boot times. I love how it is a performance boost not requiring improved hardware. That's something that will really benefit people who are upgrading existing installations. I stick with hibernate on my laptop which is quick and avoids the longest part of the boot which is the "log on" process, i.e. from CTRL+ALT+DEL to desktop

So...instead of a full shutdown, you hibernate the kernel, tricking the user into thinking they've shut down the machine. But you haven't actually shut down the machine--which over half of users would prefer you do. And in order for me to do a real shutdown, I have to remember to turn on some cmd prompt shutdown switch? Am I supposed to remember that before swapping out a new video card?

These are all great improvements, and I can't wait to get my hands on a beta! But even more important to me than faster boot times (my W7 laptop already boots in less than 30 seconds with an SSD) is the number of times I have to reboot. I actually totally get the point of rebooting for Windows and Driver Updates, but why do I still have to restart for a computer name change or joining/leaving a domain? What about enabling/disabling UAC? I hope these are two things that can be addressed in Windows 8.

I agree with Chen. You seem to be over-relying on user usage metrics. More people should be encouraged to used hibernate as it is superior to all other options. People probably don't use it because either they don't know about it and just choose the default, or because they have driver issues or IT admin has disabled hibernate.

... another reason is also that the IT admin has disabled the ability to set the default action of the physical power button to anything other than shut down.

Nice article and work. Wouldn't it be nice to also be able to save snapshots (almost like a hibernate) at regular intervals and/or during reduced activity, so that in case of loss of power or blue screen the system can at least partially recover from a "backup" snapshot? Some users are more affected by others than this, and you would almost magically mitigate what has been a very frustrating computing experience (i.e. total loss) for decades. Also, I would love to see in your stats how many people leave their machines always running (24x7 or 24x5), and some data about the different durations of times for which a machine is powered on, but is unused. Perhaps such data could help understand these behaviors, offer an alternative, and create even "greener" systems.

This all sounds like good progress. A related issue I have with laptop standby behaviour is that if I tell Windows 7 to shutdown/hibernate, and then shut the lid on my laptop, it will go into standby (as it would under normal operation). This even happens when windows has got to the final stage of shutting down 'Shutting Down'. Sometimes this means it runs out of battery or I have to wait for it to finish shutting down to start up again next time I open the laptop. It would be much better if it could set some flag once it starts shutting down/hibernating, which would (optionally) disable the close-lid standby behaviour.

Faster boot time is always welcomed, great work! For me, however, the part that makes me waiting the most is after login. Even though I have only those programs in my autorun that I really need (antivirus, feed reader, IM client) I am still waiting 1-2 minutes until I can properly start browsers or other applications. A few years ago when I increased my RAM to 2gb, that had made a huge difference in startup time. But when I recently got a laptop with 4 gigs RAM and a significantly better processor, boot time almost remained the same. I guess the bottleneck is the hard disk. Starting applications while an IO-intensive process is running in the background (such as starting autorun programs or copying files) significantly slows down application startup. Therefore I think making more use of IO priority mechanisms (i.e. giving autorun programs a lower IO priority, performing file copies with a lower priority) should improve startup of programs.

I still think that the boot time will have a direct impact on what each user has as software.

I can't wait to test this and see the results! Bring it on!

Dear team. First of all, that's very impressive. The idea that hibernating and resuming a session without saving open programs can speed up things is intriguing. For me, the most attractive feature is it's finally multi-core optimized. Are existing power actions like hibernation also multi-core optimized? Also, if you are reading feedback and care to reply to my genuine concerns: (I know this a startup and shutdown related, but I will include logon related issues as well).

In Windows 7, there is no progress bar indicating the hibernation status. Really annoying. I want to be able to see a progress indicator when its hibernating and when its resuming. How hard is it to do that? We need a progress bar at least while it's hibernating if not while its resuming.
Shutdown menu with useful power actions has been removed from Task Manager. So if for some reason, Explorer.exe cannot load, is crashing or we are using a different shell, we can't quickly choose power actions. Even Process Explorer has those power actions. Please bring back the shutdown menu in Task Manager. Why was it removed?
Bring Hardware Profiles feature back. It was very useful.
How about a quick way to be able to use full shutdown without disabling hybrid shutdown? Like holding down Shift when pressing "Shutdown" to do a full shutdown? Such an idea was already there in XP. With Shift held down, Standby turned into Hibernate. Similarly, Shift+shutdown can do a full shutdown.
Do UEFI systems have any backward compatibility for older OSes which do not support UEFI? Meaning, can I get a UEFI system and use Windows 8 to boot faster but still occasionally boot an older OS from it without disabling UEFI even if it takes a bit longer to boot that OS? Or will buying a UEFI system mean my older OSes won't boot?
The stance Microsoft has taken on supporting UEFI only in 64-bit Windows is disappointing. Please support it in 32-bit Windows too.
No improvements to restarting when updates are installed? I hate the dreaded "Please wait while Windows configures updates" screen on logoff and logon. Why does servicing delay logon and logoff?
For workgroups computers, the classic logon prompt cannot be made to appear in Windows 7 (like it could in XP) by pressing Ctrl+Alt+Del at the Welcome screen twice. This makes it impossible to logon to a hidden user account while the Welcome screen is enabled (when Classic Logon is not enforced through Group Policy). This is not a problem for domain-joined PCs where pressing Ctrl+Alt+Del twice at Windows 7 logon screen shows the classic logon prompt.
Because of the classic logon being removed, domain names are no longer populated on the logon screen and cannot be selected from a drop down list.
In XP, autologon could be bypassed by holding down the Shift key. In Windows 7, it is not possible to override Autologon by pressing the SHIFT key before logon. The IgnoreShiftOverride registry value is ignored.
In XP, items in the startup folder were prevented from running after logon if the Shift key was held down. This was great for troubleshooting items that caused problem at startup. No longer works in Windows 7.
Logon screen no longer shows number of running programs and unread email messages.
Changing the KeepRasConnections registry key to remain connected after logging off from a RAS client is not supported.
Mac OS X and Linux distros allow users to boot into another OS when one OS is hibernated. Like with Boot Camp, you can hibernate Mac OS X and boot into Windows. Why can't Windows allow that?
Please stop setup from overwriting any existing Linux boot managers. Hope the relevant teams are reading this. But very impressive job with the fast boot.

That's so strange that people aren't using hibernate. That's mostly all I ever do. I still know some people who think that hibernate will draw battery power and don't use it. I also notice that it's the default button in the Windows 7 start menu, when really hibernate should be the default. Perhaps if the UI explained it better that hibernate wouldn't draw any power more people would use it. I never want a "fresh state", generally the only thing forcing me to lose my user session state is patch Tuesday.

What your essentially doing with this new shutdown behavior is;

Close all apps and logoff all users. That is, elliminate all sessions > 0.
Hibernate Session 0.
Resuming Session 0 with multi-core optimized code.
Noting how fast this is, especially on a new laptop with a SSD (very rare). This is all very well, but the question is - fast, compared to what? The user now has to;
Logon
Open apps
Open files... Has the user saved time, compared to existing hibernate? I doubt it. Demo looks great, but if something looks too good to be true... ...Presumably this is occurring while some services (including drivers) are initializing, as the following statement would seem to indicate: "Another important thing to note about Windows 8’s fast startup mode is that, while we don’t do a full “Plug & Play” enumeration of all drivers, we still do initialize drivers in this mode. Those of you who like to cold boot in order to “freshen up” drivers and devices will be glad to know that is still effective in this new mode, even if not an identical process to a cold boot." Questions:
How do you hibernate the kernel, and reinitialize drivers on startup? Are you not saving the state of drivers in hiberfil.sys?
How does this effect boot time?
What happens if one or more drivers do not initialize without error. Presumably reboot will be required, because system state will be invalidated (sort of like a BSoD), and hibernation state will be lost.
Why is the reinit of drivers occurring at all? Is it so you can say to folks that they are getting their superstitious "fresh start", or is there a good technical reason for it?
Why will the public accept this sleep state, having not appeared to accept existing hibernate, or even sleep? Why will behavior change now?

@Andre.Ziegler,

do you speak for Microsoft or only for yourself when you say the hibernation progress bar was removed to speed up the process? :) How do you know that was the reason or where it mentioned so? :) I think Microsoft write a decent progress bar implementation that works with WDDM/Aero. How about a "clear and confident" way to show to the user what's happening?
I just think servicing should be re-designed so it does not affect logon/logoff performance in any way. In-use files were always updated prior to Vista too without considerably delaying logon/logoff. The three slow stages of servicing are unacceptable as a user to me if it slows me down from getting to the task I want to do.
What is an annoyance to you is a feature for some. I am sure this blog values everyone's opinions. :)

Well almost assuredly the ones that are slower both before and after in the comparison charts are probably slower machines with slower HDDs. But you can still see the marked improvements. It isn't like Windows 8 will suddenly make a Pentium 4 run like an i7, but at least it continues the Win 7 tradition of extending the life of older machines. Personally, I will never recommend a non-SSD machine to anyone now, and certainly not once Win 8 is readily available. 160GB is plenty for most folks and the speed vs. price is well worth it. Further, if you're going to compare performance with tablets, every tablet has solid state memory. I hope more laptop manufactures start offering laptops with space for both an SSD and HDD. Booting & apps should be fast, but if I also want 350GB of my favorite pictures, photos, and movies. But then I guess I can always have an external USB 3 drive with Windows 8!

Well fast re-booting (not to be confused with restarting) is essential but still Windows has issues resuming from standby mdoe which is used as often as rebooting.

It's so strange to hear that people was a refreshed state. Up till now I've only heard people complaining about automatic update because it cleared their state.

Steven, Gabe, thanks for a great post! While you mention that many users like to shutdown to "refresh" their session, one of the most frustrating elements of Windows for myself and most people I know is the shear number of restarts required from system updates. I appreciate that you commented on reducing these necessary restarts, but have you considered going even further and allowing restarts that return the system to the exact same state as before the restart? That would be an immense relief, both on my home computer and work PC.

Microsoft already has the "Restart Manager" since Vista for closing apps during MSI installs and restarting them. Why not extend it to persist across reboots and use it to restore open programs and documents as they were when the system is restarted? Close to Mac OS X Lion's "Resume" feature. (I say close because Resume apparently also saves the state of the apps themselves).

I rarely ever reboot (desktop machine) but it'll still be nice functionality for when I do. In fact I really like Stevesi's comments here "We designed Windows 8 so that you shouldn't have to boot all that often (and we are always going to work on reducing the number of required restarts due to patching running code)." One of the key reasons I can do this is because of how much more reliable sleep mode is on W7. So thanks for that!

Just please make sure that if I have my laptop set to hibernate when I close the lid (or in suspend mode, battery runs low, and hibernate needs to kick in), that no app for any reason ever can prevent this from happening. Too many times (meaning any time more than once - and it's happened a few), MS Office with a network file open has prevented this. I've closed the lid, so I don't see any notices. I pack up the computer in a tight space. And it overheats, loses all my open work in other apps, almost catches fire, and loses all battery. Unless I'm in embedded windows, never let an app interfere with hibernate / suspend!

Also it would be nice if windows provides a one click/touch button which kills all the other apps and just keeps the processes necessary for running the windows and of-course internet. Just like fresh new session. Its painfull to kills the processes manually when the windows freezes.

Guys, please focus on trying to find a way of letting people reboot their computers but come back to a desktop that has their programs and files open as though their computer has not been rebooted. Why is this an issue? In corporate environments (my team manages thousands of corporate computers) everyone has to 1) Leave the PCs on (wasting money, etc.) and 2) Reboot their PC and "lose their work" (that the term that the end-users use when they have to close out of 20 word/excel documents they have open or when an auto reboot happens). I know you guys are brilliant and can find a way to push down patches to PCs w/o having to reset the entire user sessions. This gets 100's of times worse on terminal servers. Even it was just Outlook, Word, and Excel hat support this it would still be a gigantic improvement.

Faster booting is nice and all but I'm far more interested in how quickly the system responds and how stable it is (i.e. not needing to boot/reboot very often). And the fewer times I'm required to reboot after installing/upgrading the happier I am.

I very much appreciate this. In Windows 7 too the boot time is very short, IF you dont have other applications coming up at boot time. I feel many a times applications are added to startup quite unnecessarily; in order to cut application start times they transfer the burden to what user believes operating system boot time. I understand everything after login is to be attributed to these applications. Is there anything you can do to prevent this? or bring about some discipline? or as in IE show a pop-up which says boot time could be reduced if this application is not loaded at start up - especially those which see no activity (which I am hoping can be detected from the OS).

Awesome work! I have a question though: When you mentioned that hardware changes require full shutdown, does that include peripheral devices? E.g. USB, eSATA, ExpressCard etc. When I shutdown my laptop, which is connected to a number of peripheral devices that stay in my house only, I cannot foresee if I would need to grab it and rush out of the door before the next boot up.

Actually, my Win7-64bit machine boots and shuts down faster than it can hibernate or restore. About 17 seconds from UEFI to logon screen. Could it be that when having a lots of memory hibernate is actually slower? I've got an SSD and 16GB memory.

I don't use hibernate because the majority of the time it doesn't work and never comes back from hibernation force a manual shutdown of the system. I've experienced this on several different computers at home and at work. Hibernation is flaky at best. I disable it as soon as I install the OS.

Many times when I shutdown my computer, apps like Outlook, are slow to shutdown and thereby prevent the computer from shutting down in a timely manner. Windows 7 has improved the shutdown process to add a message asking you to forcefully shutdown these slow or unresponsibv applications. However, the message does not say which applications are slow to shutdown and so I don't want to force shutdown a critical application. Please add information to the Force Shutdown dialog listing the names of the applications that would be forced to shutdown if I choose this action. Otherwise the dialog does not give me all the information I need to take an informed decision. Also, and by the way, why is Outlook even 2010 slow in shuttting down and always creates such issues? It should bhave been fied by now.

@Andre.Ziegler: without the logo animation my netbook only takes 2 or 2 and a bit full bar scrolling and immediately the login screen appears (I hope to be understood). I think the logo animation slows down the boot. I really think it's like that. Anyway, Windows used on tablets should have a faster boot to the login screen.

Great improvement however I can quickly see it slowing down heavily once apps start to open up, how about either delaying that process until later or banning apps from automatically adding themselves to this queue?

So let me get this straight: you are going to essentially increase my shutdown time (because you are hibernating session 0) and you will decrease my startup time. That's fair, but the user probably won't realize that. The laptop traveller that hits the power/function button on the laptop expects a certain behavior, and is ready to throw the laptop (with spinning hdd) in the bag after about 10 seconds. It needs to be understood that this new behavior will not inherently save time in a net/net fashion or will it? Also -- what then happens with Session 0 if it becomes 'stale'? What runs in Session0 that could corrupt it's own memory footprint that would need 'refreshing' as you mention about Session1 (user).

@Wendell: "If it starts up that fast, how will I ever be able to tap F8 fast enough to start in safe mode? Very good point. Rather than madly tapping away on F8 during startup (or Del or F2 or... to get to BIOS), there should be a way of requesting the boot menu prior to startup - like an indented switch somewhere, or via something like a BootCfg switch on keyboard that activates a small secondary LCD screen that displays boot options, or can activate an Administrator account using password for emergencies. @Jason: "Just please make sure that if I have my laptop set to hibernate when I close the lid (or in suspend mode, battery runs low, and hibernate needs to kick in), that no app for any reason ever can prevent this from happening. Too many times (meaning any time more than once - and it's happened a few), MS Office with a network file open has prevented this. I've closed the lid, so I don't see any notices. I pack up the computer in a tight space. And it overheats, loses all my open work in other apps, almost catches fire, and loses all battery." Again, a small secondary monitor might help with this, if it clearly indicated that open network file or whatever was preventing system from hibernating. @xpclient: "Microsoft already has the "Restart Manager" since Vista for closing apps during MSI installs and restarting them. Why not extend it to persist across reboots and use it to restore open programs and documents as they were when the system is restarted?" Agreed. Just adding the open apps to the RunOnce key would be helpful. @bradavon: "Please use shut down because no one has ever explained properly how hibernate works. It's only natural people want to turn off when they're done. Which is why Microsoft should've explained a long time ago, hibernate does just that too." Solution: Make the 'Shut down' button actually the Hibernate button. Add a 'Full shut down' button to the 'Shut down' button right-arrow menu. I would also have a Sleep button above where the 'Shut down' button is currently located. @Jeff Carlson: "So let me get this straight: you are going to essentially increase my shutdown time (because you are hibernating session 0) and you will decrease my startup time. That's fair, but the user probably won't realize that. The laptop traveller that hits the power/function button on the laptop expects a certain behavior, and is ready to throw the laptop (with spinning hdd) in the bag after about 10 seconds. It needs to be understood that this new behavior will not inherently save time in a net/net fashion or will it?" Exactly. Where is the net time saving - or are we just trading increased shutdown time for less startup time, only to have to reopen apps and files again also? Really what i think this is really about is;

Looking good compared to non-Windows tablets (the current flavor-of-the-month).
Not chewing up such a large chunk of expensive SSD space with hibernation file, while retaining some of the benefits of hibernation. By mid-decade, when SSDs are almost as cheap as HDDs, we can go back to using full hibernation (including full user state). Until then, a compromise solution is required.

Thinking more about this, I think that all the shutdown options are just too confusing to many users - most probably don't know what "sleep" or "hibernate" mean. I think you have got it badly wrong in interpreting the user metrics as saying that users prefer a clean new session every time - maybe in Windows XP I would have liked a clean session, but with the new Windows 7 taskbar I do not. A better solution is to simplify the options down to just Hibernate ( perhaps renamed to "switch off" or "shut down") and "Restart". Would this not make more sense? Surely with upcoming technology improvements such as SSDs the hibernate function can be vastly improved to at present?
Anonymous
September 09, 2011
Another technology that would also make "hibernate" the default behaviour would be new non-volatile memory technologies such as Magnetoresistive RAM. With such blazingly fast non-volatile memories, then volatile memories would be merely used as caches in any such new computer architecture.

@Steven Sinofsky IMPORTANT READ!: Dear Microsoft, This has nothing to do with the topic of this post, but I would like to talk about issues regarding the Windows Snap feature. As I've been reading other Windows 8 forums, I've noticed that many have been complaining about the 16:9 issue. Understandingly, Windows Snap should only be available for widescreens, but it doesn't need to specifically be 16:9 . Many believe that 16:10 deserves a chance for this new feature. Although this is a problem stated by many, believe that the statement could have been misinterpeted. Perhaps, as I thought I might have heard, that Windows Snap is available to any resolution above the standard 1365x768 resolution. Most WXGA+ 16:10 monitors are above that resolution (1440x900), so if that's the case, then their shouldn't be MUCH of a problem. If not, then you may want to take consideration into this. Thank you for your time. P.S.-If this not the right time to post a comment like this, then I can wait until the moment comes.

@TheTechFan & @Johannes Duschl – question on whether quad core vs. dual core makes a difference to Win8 boot. It totally depends on the combination of processor and disk capabilities on your system. We’ve seen either CPU or disk be the bottleneck. The one thing I’d say is that if you have a fast SSD (i.e. read times in the ballpark of 200 MB/s or greater), going from 2 to 4 cores improves Win8 boot / Hibernate resume times. The SSD is bringing in enough data to keep more than 2 cores busy decompressing the contents of the hiberfile.

Pretty cool, definitely improvement where S3 standby is not viable and there's lot of memory to hibernate. But I'd also like to see creative improvements on application startup times, ability to make superfetch more aggressively load used apps after cold boot on 6+ GB systems and especially improvement on explorer file name search speed when you are searching files or folders by name only. It takes explorer in Windows 7 ten minutes to search through couple cheap & common multi-TB hdd's with tens of millions of files. In comparison, open source NTFS MFT search can perform this in seconds. What is being done about this?

From my perspective it is very important for you to keep the Windows 8, 9, 10 naming convention - to identify in people minds that from the very solid foundation of Win 7 that thing are going to continue to evolve as a grounded product rather than take detours on odd naming which dilutes and resets the momentum, Please allow the colo of the tiles to be changed - but don't just add a palate of several colors to choose - I find this very irritating in One Note that the tab colors are set and they are not ideal shades - all a 'more colors' option - it would be nice to have background images and 90% transparency on a tile.

This dialog can take up to 10 minutes to pop up!!! I run several Windows 7 machines, and this is a common experience on all of them. It really is the single biggest usability problem in Windows 7.

Looks great, and very interesting to see those stats. Suprising to see how few people use hibernate though. I think the biggest issue with shutdown/startup in Windows 7 is when it comes to installing updates though. Being able to install and then shutdown is great, but while I understand why it's done, it's really annoying when you then start Windows and it has to sit there for ages completing the installation before you can use the computer. Personally I'd love it if after the initial installation completes Windows rebooted instead, completes the final install process and only then shuts down.

My friend says : "Regarding the fast boot time article, i think it's a good thing but it shouldn't be a priority, because users turn the pc on one or two times a day, tops. So it's not that big of a time loss, although i understand the average user doesnt want to wait. But Win7 is already fast at boot, if you use a lightweight AV. Qo, ok, good, but not top priority IMO."

I think it's poor engineering that desktop systems don't at least come with a battery backed power supply as standard. Unfortunately there is very little innovation in the PC hardware space (unlike the competition). Microsoft could be pushing for improved hardware via their logo program, but seem more interested in consumers having vast choice. That is, lots of hardware vendors selling minor variations on a decades old theme. However this is not necessarily surprising considering the number of cheerleading comments to this post, which is essentially about a half-baked version of a power mode that no one currently uses. These folks are easily impressed!

Allegedly windows 7 boot up about 30 seconds. My fresh and first-turned-on windows 7 (that I buyed because the before, laptop manufacturer's windows 7 was very slow and boot up time was critical, over 3 minutes), then it booted up about 1 minute. I'm now using this (since 2 months) and its boot time about 2 minutes. I really hope windows 8 will not like this, because windows 7 not as fast as say it... I hope in service pack 2 for windows 7, you do something for boot up because really slow for me. I often go to drink or wash my hands (without joke!!!) while my windows 7 start up. Often after those still booting up! I can't do anything, I tried every antiviruses and performance optimalizer but... those don't good. If windows 8 will boot up after 3-4 months like this (or 4-5 seconds later) it will be perfect. I hope it.

I'm not paying for that. My system already boots in 10 seconds and if I use hibernate it takes 5 seconds. I think releasing a demonstration video with no real-world applications, like workgroup login, or system details is simply false advertising.

I second the the idea of having the system auto-logon and lock so that post-boot operations can take place while I'm getting my coffee. I also think that the default option for shutdown.exe should remain as it is and the switch should be used for enabling the fast shutdown so as to not break existing applications.

If Windows 8 will integrate more software, like Hybrid-V, windows media player with all video support (mkv, flv, mp4), a desktop recorder, an audio/video converter, a better bluetooth organization and connection/reconnection, a better development in paint (add please support for trasparent background) (for example add an option to use it for basic users and professional users), a better benchmark tool and a software that control the temperatures of the hardware, Windows will don't need of too many external softwares that make windows slower, and the speed will not be too much serious.... But for now very good results ;)

I have a few questions not addressed in the blog :-

Are more services being set to trigger to achieve this? What is the time when the desktop is completely usable (fresh Windows 8 install on a new pc)?
What happens if I shutdown the pc, install new hardware, and power on? From what you said, since I did not use the option to do a cold shutdown, the hardware will not be recognized, right? This is unacceptable - at the minimum, Windows should detect new hardware and discard the hibernated session if it finds any? Hw enum should not take too long.
Are there any other scenarios where hibernating the kernel session is going to cause problems? Like others have said, hibernation is not exactly foolproof.

I have been using MS OS products since DOS 1.0 and Windows 1.0. As Windows has grown, boot times have noticably declined, even with increased CPU "horsepower." This will be a very welcome change. The faster the better, so we can get to work! It would be terrific if the same concept could be backwardly migrated to Win7! I have beta tested almost every new Win release. I look forward to beta testing Win8, when it finally arrives. I don't yet have atouch screen for my desktop or laptop and probably will not for some time. So, it will be inetresting also to see how and whether the new Win8 UI allows us "old timers" to revert back to some "power user" mode that relies on the traditional menu struture, rather than pictured tiles. Tx.

I think that in W7 the boot time was nice improved from previous versions (since Windows 2000 at least). Get better boot time in new Windows version will be a really apreciated stuff, but the main question here is about the performance time to run weights process.

Guys, Guys, don't get so excited. It most probably doesn't boot the entire OS. It's just a start screen. to make it fast they first will load the kernel itself and the application you have chosen, then the rest of it... it's impossible to load the entire OS this fast!

@Brian Amstutz - Yes, when users select "Shutdown", Windows 8 has the new behavior described above by default. After completing shutdown on Win8, yes, it’s safe to unplug a desktop machine. @Behzad - The mechanism described above loads/resumes the kernel, session 0 services and other infrastructure to get to the login prompt. I.e. you can think of the Win8 boot process as having as many pieces of the OS loaded/initialized as Win7 does when you're at the login prompt after booting.

No meaning to write here anymore....they have already decided the most things about Windows 8 according to some sources i have. Windows 8 will f.ex be released with the same versions as Vista and Windows 7, no more no less. Whatever we demand they don't care about. If they did listen Windows 8 shouldn't be Windows 7 SP2...as it seem to be. No, it would go further back to like 2000 or XP, the versions people really love.

Yes, vey nice, Windows will be up in 10s! However, let's not forget that you need to use the apps , not just the OS. If the app and user session is fresh, the loading of those will be similar. You essentially save up in driver loading time. Driver re-initialization i still performed. If Windows 8 uses the app pre-fetch feature similar to Windows 7, you will have a loaded OS but you will still be waiting for the fetching of the applications which is, in fact, what you need to use a PC. Summary: Marketing, you load Windows very fast. It does not mean you are able to use the system yet, though.

Currently downloading the developer preview, and looking forward to tests on both an Acer Iconia Tab and my Sony Vaio. The Acer has an AMD x86 processor, while the Vaio has an Intel Core i5. It will be interesting to compare the differences between how the new software affects both hardware platforms, though I wouldn't say the machines are equivalent in any sense of the word. My Vaio is a power-house compared to the Acer tablet, but I'm looking forward to testing out the new touch interface compared to the regular old mouse and keyboard. I thought I'd have to wait a lot longer for this!

If Windows 8 is going to be using EFI or BIOS have you already been working with the System Center team on the changes to SCCM? When you use SCCM to build it tags the system based on the BIOS ID. One issue you have with using SCCM to put a windows image on Mac hardware is that EFI has no bios ID.

And for those who feel slow boot on their existing win Xp/Vista/7, type msconfig on run, then disable unnessary services and programs to start with windows, your system will boot fast. For example, my DELL 1720 laptop with Win Vista buisness with 130 GB of program installed boot in 33 seconds. That is pretty good.

A major problem with the Windows 7 shutdown sequence is the screen that comes up saying which applications are not closed. The problem is that it comes up way too quickly. In Windows XP, if an application needed my input before closing (e.g. to save a file), I could switch to it, give my input, and then the application would close and the shutdown process would continue. In Windows 7, if an application is waiting for input and doesn't close almost immediately, then the screen comes up saying that Windows is waiting for the application to close, but I can't switch to it to give my input to allow it to close! I have to cancel the shutdown process, switch to the application, give my input and allow the application to close, and then restart the shutdown process. If there was another app that also needed my input, I have to do it all again. It is just a huge waste of time. Please remove this behavior and return to the Windows XP application shutdown process.

Searched for the way of the pass-by of such casus,but without результатно and happened to переустанавливать Windows. So here is me and came the idea-offer about alternative of the loading internet контента at the beginning initially started process Windows. But тоесть-give several buttons on determinations relationship with интернетом before entering the mail or password in system,or button for acknowledgement of the automatic connection internet контента not so-so before entering the password. And to become,such here is remark-define the list obligatory combination buttons for usual PC (primer-win+q,Win+R,Win+U,Win+P and etc and publish these positions of the buttons.). These pair(vapour)s of the buttons with plus in work will provide that a few function for PC that are submitted for flatbed PC,mobile telephone and etc that with touch дисплеем. And these buttons will подрожать such actions. Though such and are present,but not on all actions.

A question. Will the Boot splash screen be user customizable (or at least let the user select the background color)? Or will MS make it the same uncustomizable screen with a black background color? Also is this thing about not allowing the user the possibility of modifying that screen because MS want to keep users from changing the background color to something other than black, white or gray and/or changing the animation to something other than the windows logo? Check my previous post about it here: blogs.msdn.com/.../engineering-the-windows-7-boot-animation.aspx

Like others have said, I wonder how Win8 will perform with a bunch of applications installed, increasing the size of various databases that have to be verified every boot, creating drive seeking which can decrease throughput up to 90%.
