Some.
The thing where I can press the windows+arrow keys to do things like maximise a window or half-maximise a window onto the left or right side of the current screen is pretty nice. :)
The start menu having built in substring text search over Start Menu shortcuts (ONLY!!!) was briefly really good. Unfortunately Microsoft subsequently ruined it by adding in web search too in the same place. :(
The start menu recognising when you type in simple arithmetic expressions and showing you the answer is really good. Unfortunately it only sometimes works, while the other times it does a bing search instead. :/
