I installed xp and when i go to activate windows, a window comes up saying i need a new product key

 

if you have a legitimate copy of windows XP then enter your product key and it will work, if it doesnt work and your certain you own a legitimate copy, get on the phone to microsoft and they will give you a new product key.

Otherwise go buy a legal copy
