I used win10 for a while but to gain full control just like before you have to disable "admin approval mode" in your group security policies. Disabling UAC like that prevents you from using apps (which doesn't bother me) but in win10 everything is an app! even the calculator, so it actually became a nuisance. There's also still many bugs present in the 10240 build such as serious ownership issues. Also I hate the new context menu of win10, the animation is so damn slow. Despite all this I was okay with sticking with it for the time being until my drawing tablet drivers wouldn't support win10 at all so that's why I moved back to 8.1 lol.
