I am battling with the same error 80070005 and unrecoverable error if I try to re-install Windows Update. Has anyone had a satisfactory fix from Microsoft yet? Also note from the Windows Update log file it appears to be stuck on what some people are calling a stealth update to Windows Update itself:- SelfUpdate handler update required: Current version: 7.0.6000.374, required version: 7.0.6000.381 Call me paranoid if you will but maybe this is why I can't find anyone that can fix it yet other than people suggesting re-install of Vista or suggesting fixes that used to work on older OS. Help Please.
