Best way to go from Win7 Premium to 7 Professional (Full edition)
Installed Professional 7 with Disc full edition on my PC 4 months back. Now I am getting a new PC, and it has 7 Premium built in, arriving tomorrow.
What I am enquiring is, the best way to get the Premium back up to Professional, as I am really hoping a Clean Install isn't the answer considering the effort it was for my old /current PC.
