To get by Windows Update when it starts checking for keys is to have a database of all the security updates AND drivers, updates, etc. The only problem with that would be if Microsoft started doing key checks with each update. An even smarter way for all those corporate pro users out there ( mainly the only version of xp thats pirated ) is to just find another corporate key from other corporation that microsoft hasn't contacted and changed yet. Can you say buhaha. No. Someone has to do it before we can say buhaha.
