I'm almost positive you can install Windows 8 Upgrade over your previous Windows version of choice and activate without issue, regardless of whether the original OS was activated or not. However, since 8 requires entering the product activation code during installation, the old double-installation method that worked for 7 appears to be a non-option for 8.Hmmm... so I could just buy this and that's it?

I'd be running an official version of windows?
The people at microsoft said it wasn't possible, that I needed a Win7 base key before. Now that someone here has mentioned s/he has done it over a trial version I think MS people were deceiving me.
But...
Apparently there is a trick involving adding a file to the installation media that can allow one to install 8 without entering the key. The registry-command combo involving MediaBootInstall and slmgr appears to still work if you get 8 installed but can't activate it as well.
