If your beta testing Windows 7, you may experience random crashing of explorer and msiexec.exe when trying to start Windows Update or install anything that uses an MSI based installer. The issue lies with the SQM Client which is part of the Customer Experience Improvement Program.  It seems that ANY process that calls WinSqmStartSession in ntdll.dll will start crashing when MachineThrottling is enabled in the registry, which seems to happen as a result of CEIP running.

Here’s the method to disable the anonymous usage data (CEIP), until Microsoft fixes the issue and issues a hotfix or a new build:

  1. Delete the string values (Except for (Default)) in HKLM\Software\Microsoft\SQMClient\Windows\DisabledSessions
  2. Start gpedit.msc
  3. Expand Computer Configuration, expand Administrative Templates, expand System, expand Internet Communication Management, and then click Internet Communication settings.
  4. In the details pane, double-click Turn off Windows Customer Experience Improvement Program, and then click Enabled.
