I see there are a few problems happening with this update. I am having\nproblems as well. I'm on WinXP SP3 and using Windows Live OneCare. Kb958215\nkeeps wanting to install over and over again. It never has an installation\nerror that I can see. Then when I reboot it tells me I need to ChDsk and\nfixes various errors on my hard drive. Microsoft needs to fix this update. I\nseriously doubt it has anything to do with anything other than a faulty code\nline or something.
