Here is a list (from Microsoft) of Programs that have conflicts with SP2. It's a long list including AOL, Nero, Starcraft, and even many M$ Products!
Apps that act "differently" in XP SP2
I also find it funny they put "Kazaa" on there.
BTW, if you find this helpful/useful/interesting, could you please rate me up? I know this seems shallow, but I'd like to have a good rating, and I try to rate anyone that helps out. I have been rated down for asking, with comments like,
"He asked for a rating. Bad move"
But you know what? I'm being honest, and if I get rated down for trying to help out, for wanting a virtual rating that is free and takes 3 seconds to do, then so be it. Thanks in advance.
