Vista update fails: component store corrupted

  • 772

I have a vista x64 box that is no longer able to apply updates from microsoft. When I dig in looking for the problem I find this in the event log "could not be installed because of an error: 2147956498 "The component store has been corrupted."" I cannot get system restore to go back far enough to escape the problem.

Can you think of a way to fix this machine, or do I have to do a complete wipe and rebuild?

windows-vista update

    While it sounded promising the tool suggested by Martin did not work. (It refused to install). More research lead to knowledge base article 946414 which has a link to a windows update FixIt tool. The FixIt tool when run with the most aggressive(not recommended) setting fixed the problem.
