One of Windows 10′s bigger new features is virtual desktops — additional instances of the Desktop that you can use to better organize your workspace. There’s also improved snapping, and a new view called Task View that’s kind of like Alt-Tab, but it incorporates your virtual desktops as well. All of these new features have associated keyboard shortcuts to make using them a cinch.
Task View is opened up with Windows Key-Tab. It looks very like the new Alt-Tab interface, but it stays open after you let go of the keys. You can also add, remove, and manage virtual desktops from this interface.
Windows Key-Ctrl-Arrow (left or right) switches you to the next virtual desktop on the left or right.
Windows Key-Ctrl-D creates a new virtual desktop. Windows Key-Ctrl-F4 closes the current virtual desktop.
Windows Key-Up arrow and Windows Key-Down arrow can now be used to snap the current app to the top or bottom of the screen (this is in addition to Win-Left and Win-Right for snapping to the left and right of the screen). Tapping these shortcuts multiple times creates different effects: Tapping Win-Up once maximizes an app; twice snaps it to the top. Win-Down once snaps to the bottom; twice minimizes it. You can also use Win-Left/Right to move apps incrementally across a multi-monitor setup.
