Customize Power Switch Windows7

By default Windows7, showing a Shutdown button on the start menu, this button as the button's Shortcut Shot down if the computer will then click Shut down immediately. Not a few people who want to expand the menu next to it to press this button and the computer immediately shut down. o..oow!
To overcome that we can change the key (shortcut) with the shutdown action, such as the Switch User, Log Off, Lock, Restart, Sleep and Hibernate. Right-click on the Start button - and then Properties.

On the Power button action select the action that will fit in this example I try to select Lock.
