I bought an alienware x51 r3 that came preloaded with windows 10.I hate windows 10.I feel like every time I use it more of my soul is sucked from body and given to the sh**bags at MS.My good friend,Hugh,sold me an unopened copy of Window 7 Home Prem 64.I wanted to ask if anyone has erased 10 and gone back to 7 and or rolled back from 10 to 7.I wanted to see what their thoughts were.Any help would be...helpful.
