I have a desktop that I wanted to upgrade to ultimate from home premium. I entered that product key and it installed perfectly. However, now one week later an error message comes up and says windows could not validate they key. You can close out of the error message, but comes back up a day later. Can you roll back to home premium, as ultimate is already installed? I don't want to buy another product key.
