15. Mouse Tricks
In Windows 7 and later Windows OS, you can easily manipulate with multiple windows at the same time. If you have 5 windows open, you can minimize them all by clicking on the top left bar of the window and shaking your mouse. The active window will remain open. Shake again and they will pop up.
