I've just upgraded to Windows 10 from 7. Despite changing all Windows power settings, when I close the lid of my Mac Book, Windows does a hard shut down.
I can get the machine to sleep by choosing that option in the Start menu, though closing the lid quits everything,.
Fine on the Apple side and seem to have all other functionality.
