I have a customer for whom Windows Update will not run at all. The OS is Windows 7 Pro.
He was unable to update Windows, so I started stepping through the procedure in Microsoft KB article 2509997. I got past the backup and deletion of the contents of the Catroot2 folder and used a batch file to reregister the Windows components needed for Update to function. I tried to run Windows Update, and it hung. I cancelled and rebooted. Now The Windows Update dialog will not come up. The Microsoft Fixit for Windows Update also hung. And now, I can't stop the Windows Update service.
Is there any hope that Windows Update will work without reinstalling everything? What do I have to do to make that happen?
