Then keychange.exe could be a tool that will change your key according to the manufacturer code sent to it. If a manufacturer code is not found then it can open a box asking for a valid key on first boot.
I can make the keychange.exe if needed.
Sounds great to me!
Is there a way to add detection for what version of XP is being used? maybe another switch on that that would insert a different key that is provided depending on if it is HOME or PRO or MCE... for those of us who like to be legit?
