I have a problem, I need to install Windows XP on my new computer for a LAN party tonight. I can get really cheap, legitamate, licensed copies from my university; however the place where I can buy them is not open this week. Would I be able to use my old WinXP then change the product key to a new one when I register? or will I have to reinstall with the new product key? Can I even install Windows with the old CD on my new computer?
