Chances are you're not using a 'cracked' version of XP.. you probably just have a corporate serial... if you downloaded XP off the 'net, your serial probably starts with FCKGW.. in which case, after SP1 is released, you won't be able to use Windows Update...
But anyways, if you want to run XP without activating, just use a corporate serial... just make sure it doesn't start with FCKGW.
I have the cracked xp, so I don't get that stupid ".NET Passport" shite. Maybe there is a patch...try searching Google for "windows registration patch messenger" or something akin to that.
i can tell you how to change the activation code to coporate
ONLY IF THE MODERATORS MESSAGE ME AND GIVE THE GREEN LIGHT. Because it will give Coporate Keys... But I will not do so Unless a moderator Says it is ok!!!!!!!!
