I have a PC that came pre-installed with Windows 8 (not Pro). I really wanted Remote Desktop, so I was investigating buying the Pro "Feature Pack", which seems to cost about $80 -$100.
But through my school I bought a full copy of Windows 8 Pro (much cheaper), which comes with a CD and a product key.
So I was hoping I could just change the product key on my existing Windows 8, but that didn't work. (The Product Key you entered will not work with this edition of Windows 8).
How can I switch it to Pro and use my new key? I'm hoping I don't need to re-install? My computer is setup the way I wanted it.
