<< Ok thanks for clearing that up guys. He downloaded Pro from a warez site and then went on to tell me that the retail version of Pro in stores doesn't have activation either. >>
To clear things up...your friend is retarded! There are three versions, XP Home, Pro and Pro (Corporate). Pro (Coporate) is NO different than the retail version. The only difference is that the coporate version doesn't need to be activated. The retail version of Pro DOES need to be activated. Tell your software stealing friend to BUY XP Pro and he'll find out.
