For me the "work around" iso creation method didn't work. I recently reinstalled windows 8.1 on a ssd drive. I just used an 8.1 key that I had to get the install to continue. I was then able to change back to my 8.0 key before activating without any issues. I didn't know about this generic key at the time though. I've been keeping up with this thread to see what your experience is.
You should be able to change your key through the system settings window on the lower right hand corner of the screen.
You can normally. The commands I posted are for if it doesn't work for some reason. Go to the full post
