I have a Dell XPS 8500 that went through a botched Factory reset. Windows only offers Windows 8.1 via the Creation Tool. I used 8.1 with a dummy key hoping that the OEM key would automatically activate it but that did not work. I used a few of the key viewer apps and they either showed me the dummy key or nothing at all. Dell assured me that the key is there and their recovery media would do the trick. I am wondering if there is any other way to do this and avoid the cost of the recovery media.
