There’s no dedicated menu option available to quickly shut-down or restart your Windows 8 computer.
Since there is no Start Menu in Windows 8, you have to switch to the desktop view and press Alt+F4 to bring out the Shut Down menu or press the shortcut key Win+C, go to Settings –> Power –> Shut down.
This is a tedious process particularly when you are in a dual-boot environment and need to switch from one OS to another.
It will be more convenient to create simple tiles, as in any other metro app, and place them on the Windows 8 desktop so that you can Shut down, Log off or Restart your Windows 8 computer with a simple click or tap.
Enter createButtons.vbs (a simple utility / script) that will automatically add Shut Down and other related buttons to your Windows 8 screen. No installation is required. You can just download the file to your desktop and double-click to create the various buttons.
