Windows 7 Deployment Pre-scan check PowerShell script

  • Artikel

I was recently tasked to upgrade roughly 5000 Windows XP clients to Windows 7.  The company uses both Microsoft System Center 2007 R3 OSD and MDT 2012 in their environment for building their base image(s) and deploying them to the enterprise.  My previous experiences with working with XP is that there were going to be client issues during this deployment project, so I built a PowerShell script to help identify problems machines as well as help rectify known problems.  I ran this script each day on the collection(s) that were assigned to be upgraded on that night.  Running this script helped us achieve a 90+ success rate for each nights deployment.  The script was constantly expanding as the project grew as more client issues presented themselves.

First, I need to mention that my client would not allow my domain network account to have admin rights on their workstations, but they did give me the local admin credentials to gain access to these machines.  I needed a way to store the local admin credentials and populate the pop-up request for each workstation I wanted to gain access to, rather than have to enter the credentials each time.  I used this one line script to create an encrypted text file that I could use in my main script when calling the credentials.

Read-Host -AsSecureString | ConvertFrom-SecureString | Out-File C:\Temp\Local-Admin-Password.txt

I used PowerShell ISE to run the script(s), so that I could see the results from the scan easily. 

Here is the full code I used:

#Purpose: Script looks at all workstations in AD Security Group, pings them to find which ones are online
#; Gets OS and Computer Model information
#; Checks to see if SCCM, BITs, WMI services are running
#; Checks to see if there is a Software Update stuck in WMI and clears it
#; Checks to see if there is enough disk space and removes CCM Cache contents if disk space is low
#; Checks to see if TEMP profile exists and adds Environment Variable for MDT to bypass error ScanState error
#; Checks WMI by running WMI Scan to repair if needed
#; Trys to wake machine up if offline
