Windows 7 comes with an interesting feature through which managing all the open Windows becomes easy. Document and program management is simplified by allowing to “dock” a window or change its size with a simple key combo or a mouse click.

To dock half size window on Left Side of Screen :

Mouse Action : Drag the Window to left

Keyboard Action : Press Win + Left Arrow

To dock half size window on Right Side of Screen :

Mouse Action : Drag the Window to Right

Keyboard Action : Press Win + Right Arrow

To Maximize window on Screen :

Mouse Action : Drag the Window to top

Keyboard Action : Press Win + Up Arrow

To Minimize window on Screen :

Keyboard Action : Press Win + Down Arrow

The key combo above would first Restore down the window then Minimize it.
