How would previous windows 7 users rate their experience they might have had with ten? Upgrading from windows 8.1 is beneficial because it gives you a start screen and all, but to me I still personally prefer 7. The only resemblance ten has to 7 is the start menu. Other than that the features and UI was definitely leaning towards 8. I liked have the transparent glass, the flipping 3d, and the Aero affects. Also would it be accurate to say windows 8.1 is it's own OS? Like if someone randomly asked me to list the OS's starting from XP and I said: XP, Vista,7,8,8.1,10 would this be right? Or is 8.1 just considered a large service pack to 8?
