I hope you bought a motherboard with the Windows product key in the BIOS.


Some motherboards come with the key and some don't.


Use the free utility that I zipped up and attached below that will show you the Windows product key in the BIOS if your motherboard has one.


If it does, you can change the product key to the new one.
