Windows 8 Shutdown

Start on the Windows 8 desktop, or in a new folder - anywhere except in the Start Menu folder!

Right-click, New, Shortcut. Paste the instruction:

C:\windows\system32\shutdown /s /t 20

(remember the space between t and 20)

Name the shortcut, e.g. Shutdown computer

Use Windows Explorer to navigate to the crucial folder:

C:\ProgramData\Microsoft\Windows\Start Menu\Programs

Paste your shortcut. (In passing you can see it's not possible to create a new shortcut here)

It's reassuring to see your shortcut amongst the other Apps.

Return to the Metro UI start screen - Windows Key is the quickest way.

Tab to your shutdown tile, press enter.
