The only problems SP2 has is that some programs won't run anymore, the firewall can be shut down with a simple command comming from internet, idiots and it auto-updates itself without asking, so it can reboot itself without asking while you're doing something important Well, that's Micro$oft for ya
That would by why I didn't get it, plus on some pcs it can cause serious damage to files on your hard drive or windows itself, thus requiring a reformatting of the hard disk. Supposedly that's only the case with illegal copies of XP but I'm not risking it
