What are the new buttons located on the Start Menu?
The Start menu now has a new Power button and Lock button. When you click on the Power button, Windows saves your work and programs in their current state, and then puts the computer into sleep mode. The Lock button is a quick way to prevent anyone else from using your files and programs while you are away from your computer. The arrow next to the Lock button opens a menu that displays the Log Off and Shut Down options plus five other commands previously not on the Start menu.
