How to Configure a Hibernate Once/Resume Many Run-Time Image
You can use EWF to enable a Hibernate Once/Resume Many environment. Traditionally, after the Windows operating system boots, the state information in the hibernation file is deleted by modifying the hibernation file. However, by using EWF, you can persist that state information from boot to boot.
You can configure an your run-time image to repeatedly boot from a single hibernation file by using EWF. By using an EWF-protected hibernation file, you can save the state of a system. Applications and services are running when the system starts, and boot time is quicker. By saving the state of a system to a hibernation file, you can continually boot from that hibernation file, allowing you to preserve state across multiple reboots.
Because EWF starts after the hibernation file is loaded, you can successfully boot from, and save to, a hibernation file.
Note Use of EWF with hibernation is only supported in EWF RAM and RAM Reg modes.
