Hi guys,
I bought a new dell desktop a while ago, and everything was fine until I used the Windows 7 discs that came with it to install Windows 7 on an old XP laptop. Since then the laptop has run Windows 7 fine, but the desktop keeps on getting the message
"This computer is not running genuine windows".
I thought installing on another computer was fine, but if not, I am more than happy to buy another copy of windows or a product key. I don't want to have to reinstall everything as it is a business computer and is always needed. Can I change
the product key without reinstalling windows and wiping everything?
If I go to Control panel - System - windows activation, there is no option to change the product key.
If anyone knows the answer I wil be very grateful.
Thanks,
Nathan.
