This is for everyone that is running the Windows XP Corporate copy with the cd-key that starts with FCKGW. SP1 is coming out shortly, and it will deactivate your Windows XP and put it in a Read-Only mode. You must change your CD-KEY now!. I am only providing the tools to do so, what you do with them is your own actions.
