Aero Snap desktop windows

One of the most appealing aspects of Windows 8's touch-friendly side is its ability to "Snap" multiple open apps side-by-side. The feature comes in very handy on the desktop as well if you need to start multitasking. Simply click an open window and drag it to the left or right edge of the screen to automatically resize it to fill that half of the desktop. Dragging a window to the top edge expands it to full screen.

If you're more into keyboard commands, Windows key + left arrow, Windows key + right arrow, and Windows key + up arrow snaps the selected window in the same manner.
