A new feature in Windows 7 is called Aero Shake. The feature lets you quickly clear a cluttered desktop in one simple shake.

If you have several windows open, you can minimize all of them except the active one (the active one being the window you want to keep open). One way of accomplishing this would be to minimize each window. However, with Aero Shake, simply click the top bar of the active window and shake it. That specific action tells Windows 7 to minimize all other open windows. To restore the minimized windows, simply repeat the process.

If Aero Shake is a feature you will never use, you can disable it. Click the Start button, type gpedit.msc and press Enter. Within the Group Policy Editor, navigate to User Configuration | Administrative Templates | Desktop. Double click the Trun off Aero Shake window minimizing mouse gesture and click Enabled.
