Windows 7 Home Premium x64 - Windows 7 Professional x64
Hey so im running my computer on an upgraded windows 7 home premium x64. (Computer came with vista) and i am taking computer science classes and got a free copy of windows 7 proffesional from MSDNAA and i have a 25bit cd key too.
How can i get windows 7 Professional on my computer?
when i used the anytime upgrade program it says my cd key isn't meant for upgrading.
