Microsoft Windows 7 has a built-in feature set, called Touch Gestures, that allows your computer to react to certain movements such as flicks and taps. Most of this feature set works with touch-screen tablet computers. However, Windows 7 also includes Aero Shake, a feature for nontablet PCs that minimises windows on your desktop when you click the menu bar of one window and move the mouse back and forth, or shake it. This action does not minimise the window you are shaking. If you find the Aero Shake feature intrusive, you can disable it.
Click the "Start" menu and type "gpedit.msc" into the search box. Press "Enter" to launch the Group Policy Editor.
Double-click the "User Configuration" folder on the left side of the window and double-click the "Administrative Templates" and "Desktop" folders that reside within it.
Double-click the "Turn off Aero Shake window minimising mouse gesture" icon on the right side of the window.
Set the value to "Enabled" and exit the Group Policy Editor.
You can also disable Aero Shake in the Registry Editor by creating a key called "Explorer" in the "HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\" directory. Create a new DWORD value called "NoWindowMinimizingShortcuts" and set its value to 1. Restart your computer.
