For Error Code 8007051a during Search of Updates, Installation of Vista SP1, Or Installing of any standalone fixes prescribed on the Vista sites, I would recommend you try the fix below. I searched for an actual fix for the above problems for over 5 months with no resolve until I tried the fixbelow and boom, windows update started working as if nothing had happened. Please check Locate “C:\Windows\winsxs\pending.xml“ Take ownership of the file Give yourself (or a group you’re in, like Administrators) full permissions to the file Rename the file to something like “pending.xml.old“ Reboot and run Windows Update Watch Windows Update find those updates you’ve been missing.
