Wondering what I should do with the Windows 8 Professional retail DVD I was given for Xmas. I'm running a pirate copy of Windows 7 Ultimate at the moment. Upgrade (I wonder what I'd lose going from Ultimate 7 to Professional 8 ) and then do whatever it is people do to get rid of Metro and make it more like Windows 7 again? What would I gain from running a legitimate copy rather than a pirate copy?
