ok recently installed windows 8, now im trying to install windows 8.1 but it doesn't take me to a place to type in the product key, it just gos straight to saying that the key cannot be validated, any ideas??
Windows 8.1 Single Language Y9NXP-XT8MV-PT9TG-97CT3-9D6TC
Windows 8.1 Core 334NH-RXG76-64THK-C7CKG-D3VPT
Windows 8.1 Pro XHQ8N-C3MCJ-RQXB6-WCHYG-C9WKB
Install with the correct key for the version you have a legal key for, once your installed activate with your KEY these keys will only allow you to install they will not activate. This is how I Clean installed win 8.1Pro from a Win 7 HP OEM, I had bought the key for $14.95 Win 8 pro in July before win 8 was released. I didn't install until 8.1 was released.
