Great Vid Steve!!! I've never used a virtual machine before, but if you keep on making videos about them, I just might try my hand at it sometime. I don't have any "extra" Windows keys, but it would be useful, after the upgrades to Win10, for when I go back to testing new Ubuntu releases, instead of dual booting. I'll probably have a ton of questions then, under "Virtualization".
Also the sound was set perfect, too bad you can't hear it through my LG Home Cinema.
