It still does. When you do a mouse click, the lock screen moves up very fast - the animation is also a hint for the future. If you have a touch-enabled device and touch-press the lockscreen, it jumps up a little and falls back down, suggesting the swipe movement. On top of that, just typing on your keyboard works.

So MS has managed to make an interface that works just the same on desktops, laptops and touch-enabled devices, and the UX isn't bad on either.

Generally yes, except I seem to run into an annoying bug where if you start typing your password too quickly after the initial unlock keypress, the password input control sometimes decides to select everything you've managed to type so far when it initialises, so your next key press overwrites everything. Plus at home I've kept the full lock screen because I actually like those random landscape pictures, but at work they've set the computers to directly boot into the password entry, which of course rather plays havoc with your muscle memory.

It hasn't changed.
