Turn off Minimize and Maximize Transitions on Windows 7

Transition animation annoys me when windows are maximized and minimized.

To disable this do the following:

1. Right click on My Computer
2. Select Properties
3. Select Advanced System Settings
4. Click the Advanced Tab 
5. Under performance click Settings
6. Uncheck 'Animate windows when minimizing and maximizing'
7. Press OK -> apply -OK

That's it!
 Enjoy
