Hi, I recently bought a new motherboard and new processor for a new computer I am building. I am reusing the HDD that has Windows loaded onto it. I am pretty confused/concerned about having to buy a new Windows key. It was Windows 8.1 (OEM I think????). Am I going to have to repurchase Windows??? If I do, why wouldn't I just be able to load Windows from the HDD?? I need some explaining, thanks.
Hi,
Did you do the free upgrade to Windows 10?
Yes:
-You will need a new key unfortunately. With the free upgrade, Windows tied your key to your motherboard serial. Since your new motherboard has a different serial it will not automatically activate. The drive would probably boot but you would receive an error from Windows saying it is not registered.
No:
If you are still on 8.1 you should be good to go (assuming drive boots fine). Just get your new motherboard drivers and have fun. At any point if you upgrade to 10, your new serial will become tied to the motherboard you just purchased and installed!
Hope this helps.
