Hi, so I have bought legitimate Windows 7 home-premium 64-bit, and the person said that I could upgrade to windows 8 if I wanted to, but is it possible to do it? and how?
When you buy windows 8, you buy the upgrade version of the OS rather than the entire OS (it was this way before, not sure if it is still the same... anyway ask in any store).
I suggest you give the beta a shot before you buy Windows 8. Many people are feeling like it was the wrong direction for the OS to go. I personally hate in on PC, it may be great on a tablet or phone, but on a PC it leaves a lot to be desired.
