images/news/windows.jpgMary Jo reports that a number of Windows 7 Beta testers have come across a bug that crashes the system randomly whenever they try to start a Windows Update or install anything using Microsoft's MSI installer. Enthusiast Chris Holmes claims that many users have started experiencing random crashing of explorer and msiexec.exe when trying to start Windows Update or install anything that uses an MSI based installer. Some have gone to the extent of reinstalling the beta.

Rafael has discovered that the fault arises from the Software Quality Management (SQM) Client which is a part of the Customer Experience Improvement Program (CEIP). It seems that any process that calls WinSqmStartSession in ntdll.dll will start crashing when machine throttling is enabled in the registry and when CEIP is running.

The suggested workarounds are as follows:

thanks for that scara. i found however that i had no entries (other than default) under the last spot of the tree, so i deleted the entries under sqmclient (other than "default"). seems ok. i didn't blow up yet, dvdfab still sucks, nothing new :roadrunner:

I couldn't install Diskeeper 2009 because the MSI installer crashed. This is the fix that worked for me...

start regedit
navigate to HKLM\Software\Microsoft\SQMClient\Windows\DisabledSessions
rename MachineThrottling to _MachineThrottling

Found it here... 2/3rds the way down. MS Technet

Already posted the way to solve it, didn't know it was a bug...

(btw, edited your post WFO, had some ugly strange bug-problem with quoting the main post, btw, you don't need to quote the article)
