How To: Fix The Bug “Windows Update Crashes Windows Explorer In Windows 7″
When you try to run Windows Update from Internet Explorer (Safety – Windows Update) in Microsoft’s new operating system, Windows 7 or sometimes when you try to run Windows Update directly or installing an application, the explorer session might crash and stop responding. Microsoft has identified this issue in Windows 7 may be related to a configuration change in the Customer Experience Improvement Program (CEIP) client.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. To resolve this problem, try any of the two methods.
Method 1: Using Windows Registry
- Type “regedit” in the Windows 7 Start Menu Search box or in Run dialog box and hit enter.
- You’ll need to provide administrative confirmation if User Account Control(UAC) is turned on.
- Navigate to the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\SQMClient\Windows\DisabledSessions
- In the right pane, locate the keyword “MachineThrottling”.
- Delete or rename the entry.
- Close Windows registry editor and reboot the computer.
This should fix the problem.
Method 2: Using Windows Command Processor
This command prompt script simply removes the configuration change, and will prevent future CEIP related crashes.
- Click on Windows 7 Start orb and type Command in start menu search field.
- From the list select and right-click Command Prompt and select Run as administrator(This will give you an elevated command prompt).
- When the Command Prompt window opens pate the following code:
reg delete HKLM\SOFTWARE\Microsoft\SQMClient\Windows\DisabledSessions /va /f
- Press Enter to run the command and you should see “The operation completed successfully”.
- If you see “ERROR: Access is denied”, please make sure you followed Step 2.
- Close the command processor window.
