Hi, I was wondering why you have to activate Windows xp Pro? What happens after the 30 days if you still have not activated xp? Why would you not be able to take computer back cause it has been activated? The reason I ask is cause i brought a laptop and it had pixels missing so i took it back and cause I activated windows they would not do a straight swap. They have to change hard drives over or something. One big headace. Cheers Richard Look forward in reading any replies.
