That update has crashed a lot of PC's..., and nearly crashed mine. My wife attempted to update XP on my PC with this service pack.., and we had nothing but problems. The computer wasn't starting correctly..., just a big mess. Ended up having to revert the system to previous and said screw the whole thing. My wife checked some forum and found a whole slew of people who posted complete system crashes trying to install this service pack.
