Ok, so heres the story: Back when the Windows 7 RC (Release Candidate) came out, i decided to installl it. I got a trial key from the Microsoft website, and everything worked fine. Now i bought the windows 7 home premium 3 pack and want to install it on my computer. The problem is, I dont think it will let me downgrade from windows 7 ultimate to windows 7 home premium. Does anyone know? Because it would suck if i had to find the restore disc for my laptop, restore to Vista, then upgrade and reinstall all my programs and files. So does anyone know?
