Has anyone who is running Vista had any problems with the 8th January security updates? All of my XP machines updated fine, but I had a call from a friend running Vista saying that their machine had locked up, and when they managed to get it restarted they were getting errors that Security Center was unable to start. Going on to their machine with Remote Assistance all the Security Center services were disabled. Starting those up manually seemed to resolve the problem with Security Center errors, and didn’t seem to cause any other adverse reactions (yet) – so I’m assuming something went wrong in the update. Anybody else had any similar experiences?
