Recently I had the misfortune of having my laptop stolen out of may car (luckly not my work laptop!). Thing is I still have the XP pro cd this came with at home which has the serial/product code on it - this wasnt on the laptop. In fact I had installed a different OS on the laptop so the product code is not in use anymore, nor can it be in use again since I removed the copy of XP from the laptop when I installed the new OS.
Can I request MS deactivate this copy, surrender the CD with product code holographic sticker on it and request a replacement product code or something along these lines?
