How to fix crashes in Windows 7 when install Updates or programs

There have been reports of some Windows 7 beta testers that are experiencing installation errors with Windows Update and third-party applications such as Java and Flash. These errors will commonly manifest as crashes of Explorer and MSI-based installers. These problems may be an issue related to the Customer Experience Improvement Program, or CEIP, client, which is also known as SQM. If you are experiencing these these issues, Microsoft has provided a workaround that may resolve these problems. Please note, any machine that’s currently not affected by this problem does not need this fix, nor will any future installations or upgrades require it.

Detailed instructions:

• Select and copy the following to your clipboard:
  
  

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

• Click on the Start button, then click on All Programs, and then on Accessories.
  
  
• Right click on Command Prompt and then select Run as administrator.
  
  
• In the UAC prompt, verify that the program’s name is Windows Command Processor and then click Yes
  
  
• Right click on the Administrator: Command Prompt window’s black area, then select Paste
  
  
• Press Enter, you should see a message stating The operation completed successfully.
  
  
• If you see a message stating ERROR: Access is denied, please make sure you followed Step 3.
  
  
• Close the Administrator: Command Prompt window

This problem occurred when Microsoft deployed a configuration change. The above fix will remove those changes, the Registry keys, in order to prevent further CEIP related crashes. Microsoft has also removed this configuration change to that the issue does not occur in future builds and updates.
