windows vista SP2 product key finder

It will be on the original Media or if it is a HP or Dell it will be on a sticker on the front/top of the PC.

that is right but the sticker is not there.

Try belarc advisor

same result..... the belarc advisor show everything in my PC, i thought it will show what i am wearing also !! ;-)

Belarc would have been my first choice also but you can try one of these, if not you'll need to contact microsoft customer support to receive a replacement key.
