Moving windows 8 around is trivial. Most of the time it just activates. Occasionally it makes you phone them which takes about 3-4 mins.
However when you have a VLK and you don't notice that the KMS server has fallen over, shit hits the fan on an epic scale...
Idiots guide to moving it from one machine to another?
Just install it from scratch on the new machine with the same key, copy your files over and delete the source installation. Don't ever move it or move disks - it will shit a brick.
Did I say that I had the professional upgrade! If I tried to do that, it would moan that there wasn't a copy of Windows on the other machine that I was trying to install it on. Even though when reading the license - I am entitled to move it. I guess there's always the hotline...
The other point that I raised was that I suspect I'd loose my media centre upgrade - well I assume I would, which frightens me a little, as it was the main reason for grabbing Win 8 in the first place. But I digress.
Snag the image for the full version and use your key on it - it'll work fine. I've done exactly what you have.

MS don't seem to have sorted the licensing model, to make it convenient with their OS, I have a copy of Windows 8, that I want to move from one machine to another at some point, and I'm sure it will be non-trivial. Not to mention that I'll loose Windows media centre most likely in the process. Even the install for Windows 8 for me was an incredibly convulted process at the time.
When DRM impinges upon usability, and convenience - it's just a complete pain in the backside.
