Install windows Xp over windows 7 When asked where to install XP, delete the current windows 7 partition(Sorry been a while). If you're thinking you're gonna save all your applications and settings, not happening. You can't upgrade to 7, or downgrade to xp while saving everything. Unless you're Vista. If for whatever reason, XP cannot be installed over 7(doubtful), you could run Killdisk, and completely wipe the drive in question, and then freshly install XP. But I love windows 7. I'd never do that. Gaming is smoother, and bugs are nearly non existent... By the way, you may want to change your thread title. Moderators, and people in general sneer at single word titles It just doesn't say enough about your problem. You might have gotten a quicker response otherwise.
