Been using Windows 10 for 2 days. I actually like it over Win 8.1. Got rid of the annoying charm bar? that kept coming in from the right side of screen and the time/date box from the bottom left of screen.
A few other features are good also.
I had the beta version when it came out a few months ago and i like it will be updating to ful here soon, i like the fact it fast boots almost like a phone or tablet. also brought back the the start menu.
