OK ...
Since you found Windows 10 to be an "easy transition" could you enlighten me as to what some of these scary differences might be? I'm really at a loss as to what you might be talking about. For that matter, could you explain how Windows 10 is "optimized" for a touch screen? Perhaps there's some sort of touch feature that I'm unaware of ... I've only used it for 10 months on a desktop/keyboard/mouse.
Seems you just want to talk to somebody (Did your dog die?), have a contentious argument to show everyone how smart you are or are just being a jerk.
I’m leaning toward the jerk angle.
