Super cool key short cuts

Windows Key + Arrow: Windows Snap

Hit Windows + Left Arrow to snap a window to the left side of the screen or Windows + Right Arrow to snap it to the right. If you have more than one screen, you can hit the key combo more than once to move a window from one screen to another and you can snap a different window to each monitor edge, allowing you to have four snapped windows on two displays (or six or a three-display setup). Hitting Windows + Up Arrow maximises a window while Window + Down Arrow minimises it.
