How can I upgrade Windows 8 OEM single-language to Windows 8 Pro with a Volume License Key? I use the Add Features to Windows 8 -> Enter the volume licensing product key and it does not accept it. It shows "This Key Won't work"


You can't upgrade to a VLK. You need to have it installed from the DVD made from your VLK provider
