I believe you have used windows for over 30 days without activation, or you have recently upgrade hardware.

you need to activate windows within 30 days once you get it, you know.

If you recently upgraded hardware, do it one at a time so this won't happen.

Try calling microsoft you you can have you copy of windows back.
