Windows Keys Extender
Information
In Windows 7, I really liked an opportunity to change the position of the windows by pressing hotkeys Win + (Left | Right | Up | Bottom):
- Win + Left - window attached to the left side
- Win + Right - window attached to the right side
- Win + Up - window is maximized
- Win + Bottom - window in the normal state

Making this work with Windows Vista and XP was not a difficult task. Also application will give you an opportunity to move windows from one monitor to other.
