Running Vista x86 sp1. The Windows Update UI has been sticking on the
"Checking for updates..." screen whenever I tell it to check for updates
since early June. Each time it shows the green bar, but never gives a result
set or an error message. Figured I'd wait until Win7 to bother with it, and
ignore the warning that Windows can't check for updates from the task bar,
but now my Zune drivers are stuck and I need to run update for new ones.
Funny thing is that there have been Defender definitions and .net framework
updates successfully installed by the automatic update process over the last
few months according to the update history. But when I select "Installed
Updates" from the Windows Update left nav bar I get zero results.
Tried manually installing the Windows Update client via KB support article
949104 (http://support.microsoft.com/kb/949104), after stopping the BITS and
Windows Update services, but it fails to install with a "Windows Update Agent
Installer Fatal Error-- Windows Update Agent Installer encountered
unrecoverable error." Also tried Microsoft Fixit 50202 on normal settings
and had no noticeable change.
Suggestions for things to try next? Or other information that is needed to
