I finally caved and started using my laptop to take notes in class and holy crap can I say that Microsoft really got their game together for touchpads. I downright HATED touchpads for years and years and would adamantly prefer a mouse in every situation. I got my laptop last year with 8.1 and the built in Asus gesture software worked alright. Two fingers to scroll, and pinch to zoom (bit clunky), were used regularly. Now I'm using my laptop more and frequently using multiple Windows with a Powerpoint open, Blackboard open, Word open, and Outlook open, I can still easily use a trackpad. 3 finger swipe up will instantly bring up all my windows and I can click to switch easily. Swipe down with three fingers pulls up the desktop and three finger swipe side to side flips to the next windows open. Once I got used to it, which took about 10 mins, I was able to navigate almost as well as I can with my mouse and dual screen set up at home.
I'm unsure how much of that functionality is purely built in, or just improvement on Asus' part. I know some generic touchpad drivers were installed automatically, and I think that's where the gesture support comes from as it feels much smoother and "lower level" than the Asus software I had on 8.1. I sit in classes surrounded by Macs with their super smooth UI's and fancy animations. My Windows machine used to always stick out like a sore thumb, but now the whole "smoothness" advantage of OS X is nonexistent and even eclipsed in speed by W10 features.
Windows Defender still has almost zero options though, which is annoying as I can't schedule scans or anything really except turning it off completely. And even that is just temporary.
