OK, this isn't really a security question, but I figured I'd start here. working on a friend's computer who had to replace a hard drive through a warranty service, at which point MicronPC installed XP Home without any means of activation. We tried going through Microsoft, but they've been completely unhelpful. Luckily, I'm a college student and could get XP Pro for under $10, so it's been bought and installed. I don't know how to uninstall Home now, it won't run past the login screen without activation, and I can't find any easy options to simply uninstall it while keeping Pro. It's got to be fairly easy... any help?
