No I don't think it is that, I understand that new Windows software is only valid temporarily until you get an identification number confirmation from Windows either on line or by telephoning their worlwide support. The reason being to prevent someone using an unlicensed copy. I believe it is is now standard on XP but I think it came in on earlier software also, so I don't want to go to W 2000 if I get stuck with this approval cycle. Any ideas ?
