Can I Transfer Windows 7 from One Computer to Another?


My old computer was originally xp, then I upgraded to WIN7 and now it's finally dead. I want to install the windows 7 disk I bought on my daughter's computer because my computer is xp. How do you transfer the license from one computer to another? I entered the product key on the box, but I got an invalid message. Fair enough, the old computer is still registered, so how do you unregister and then re-register. Thanks!
