I had to reinstall XP over the weekend. After doing so I went to the Windows Update site and starting downloading the listed critical and recommended updates. While I was doing so, I received four of those system shutdown messages that I have I read [I think on the Windows site] are related to the sasser worm. They have since subsided, my firewall is in place, and everything seems OK.

However, when I look at the Windows Update site it says there are no updates available despite the fact that several updates in update history are listed as having failed.

[A few of those that are listed at the bottom as "FAILED" are also listed at the top as "SUCCESSFUL," but not all of them.]

Can I assume that subsequent updates I downloaded after the ones that failed took care of them? If not, how do I get the "FAILED" updates?
