When i was browsing through my system tools today in XP, i noticed one tool called Register Windows XP, which got me wondering. If i formatted my HDD, and re-installed XP on it, when it asked me for my registration number, would it accept my old one, or would i have to call microsoft or something? if it would accept my old one, how would they know i didnt just give my CD's to a friend and he would use my key?
