That surprises me. I thought that update KB905474 was one of those updates that could not be removed. I can't tell on my computer, since I never downloaded that update. I am loooking for info. for a friend. I did check my updates however. Most of them can be removed. However I do have three that can not be removed. A security update KB890046, An update for Windows Media Player 10 KB911565, and a Windows Genuine Advantage Validation Tool. This last one does not have a KB number, but all three say they can not be removed. If that KB905474 can be easily removed, why is it giving so many people problems like crashing etc. ?
