Some Windows 7 beta users recently started noticing that Explorer and some MSI-based installers were crashing or just not working properly. The problem was discovered to be in the Customer Experience Improvement Program (CEIP), and disabling the feature fixed the issue. However, Microsoft has posted a second way of fixing the problem, simply deleting the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SQMClient\Windows\DisabledSessions. The company notified Windows 7 beta users experiencing the issue via the Action Center about fixing the problem, and gave the following statement:
New machines installing Windows 7 Beta will not experience this problem. An issue related to the Customer Experience Improvement Program (CEIP also known as SQM) client in the Windows 7 Beta is causing crashes of Explorer, MSI-based installers and other applications. In order to resolve the issue, impacted customers need to run the following script from an elevated command prompt. This script will stop crashes related to CEIP.
