Windows Update Error 8000FFFF (Vista)
While trying to upgrade Visual Studio 2008 to SP1 I kept getting a vague installation failure message. After a little digging I found that all Windows Updates were failing on my Vista-workstation with the message “Some updates were not installed” and “Code 8000FFFF“.
I searched newsgroups, Google, Technet, MSDN/etc and found a bunch of dated but promising tips but none of them solved the problem. Just when I was started to consider drastic measures I came across AU Check (open source) by Eddie Bowers @ Codeplex. After running his tool and rebooting the problem went away!
