I installed windows 10 and about 20 minutes later i rolled back to windows 7. Firstly windows 10 wouldn't give me a screen resolution that looked right on my TV that i use as a monitor. All the resolutions that manage to fit everything onto the screen were either too small to see/read icons and writing, or, the aspect ratio was wrong and everything looked either stretched or fat and squat. Secondly, as mentioned above some useful features that i know and use regularly have been hidden away and i can't be bothered to spend the time searching them out. Thirdly, i just didn't like the look of it. I will say though, i have the kaspersky internet suite installed and that seemed to be running fine while i had windows 10 installed.
