Win10 is great an all that. I use it on my primary desktop, but only my 2nd desktop, where I have a nice touchscreen Dell, shyt is great. Using your fingers to move around the desktop is nice as shyt. I'm keeping my second computer on 8.1. It's really only good if you have a touchscreen, but if you do, Win8.1 is the way to go. When 10 doesn't do touchscreen well at all. MS was onto something with 8.1. It's a shame than Win10 isn't has touchscreen friendly, but I do appreciate it on my main destop, where I use a mouse.
