Explorer crashes loading Windows Update program
I've run into an issue loading Windows Update that causes Explorer to crash everytime. A few days ago I tried installing a third-party Media Center plugin but the installer crashed... nothing surprising there except for when I tried to run Windows Update soon after, it failed to load and crashed Explorer. Fiddled around for a while and couldn't figure anything out, so I reverted to a Restore Point which fixed everything.Tonight I tried to install Silverlight (downloaded from Silverlight website) and nearly the same thing happened. This time the Silverlight installer loaded, I click 'Install Now', but the box disappeared and never installed. Then I remembered Windows Update had the Silverlight 'optional update' in queue, so I tried to open up Windows Update only to get the same Explorer crash. To eliminate the obvious, restarting does not fix it. Virus scan is completely clean. CHKDSK finds no hard drive errors. Etc. Here are the details of the crash:Problem Event Name: APPCRASH Application Name: Explorer.EXE Application Version: 6.1.7000.0 Application Timestamp: 494324ea Fault Module Name: ntdll.dll Fault Module Version: 6.1.7000.0 Fault Module Timestamp: 49434898 Exception Code: c0000005 Exception Offset: 00000000000ebbaa OS Version: 6.1.7000.2.0.0.256.1 Locale ID: 1033 Additional Information 1: 4d8a Additional Information 2: d29eb71c73a836dd46145293986be191 Additional Information 3: d4d1 Additional Information 4: ec74563d182390778b2662c13e8631ad

Solution provided by Microsoft... worked perfectly for me:Run command prompt as admin. Copy/paste this:reg delete HKLM\SOFTWARE\Microsoft\SQMClient\Windows\DisabledSessions /va /f

That fix is only temp. next time you restart the machine you have to go through the procedure again.

I've had same problem and i've accidently found a solution, all you need to do is to take ownership of the wuapp.exe located in Windows/system32. It's maybe stupid but it worked for me xD

The fix given by MS and listed above by jrjr2u worked for me. After several reboots, auto updating has not failed again. Understand that I run mine manually so that I can keep an eye on what gets updated.
