Just a quick comment...

Ran into this the other day and disable windows updates until a patch comes out. I have been using the hotfix to solve another seemingly unrelated issue with windows though... I've had problems with computers (all of our HP NC6320's, but two desktops also) having issues with the networking. Randomly they would just refuse to acknowledge our mapped drives or other local network resources, but would browse the web and e-mail fine. Applied the hotfix and all was fixed.

There appear to be multiple bugs in Windows Update even this long after its release.
