That probably won't work though. Most likely you will have to reformat and reinstall windows. I'm staying far away from SP2 until I get an all clear. Looks like SP2 is causing loads of problems.
Don't install it, it just slows your computer down. I installed it and it only slowed my comp down, it started to use more memory, and the windows security central is a joke! it's not worth dling imo.
Strangely enough, the sp2 beta was quite fine, but when sp2 was officially released I started having problems. I'm with bla, until this is sorted out, steer clear of sp2.
