Some Windows 7 Beta users are reporting crashes when running Windows Update, or installing third party applications (i.e. Java, Flash, and other MSI-based installers). The third-party Windows .msi installer, or Windows Explorer will crash. Microsoft has identified this may be related to a configuration change in the Customer Experience Improvement Program (CEIP) client. If you’ve experienced Windows Update or installer crashes with the Windows 7 beta, try the fix below. If you haven’t experienced Windows Update or installer crashes crashes, there’s no need for the fix. Future installations of Windows 7 after the initial beta will not be affected.

Detailed instructions:

1. Select and copy the following to your clipboard:

reg delete HKLM\SOFTWARE\Microsoft\SQMClient\Windows\DisabledSessions /va /f

2. Click on “Start”, then “All Programs”, then “Accessories”

1. Right click on “Command Prompt”, then click on “Run as administrator”
2. In the UAC prompt, verify that the program’s name is “Windows Command Processor” and then click “Yes”
3. Right click on the “Administrator: Command Prompt” window’s black area, then select “Paste”
4. Press “Enter”, you should see “The operation completed successfully”.

   If you see “ERROR: Access is denied”, please make sure you followed Step 3.

5. Close the “Administrator: Command Prompt window”

This script above simply removes the configuration change, and will prevent future CEIP related crashes. The above fix is permanent, and will only need to be run once.
