@Dr Herbie:Windows' 7 Start menu defaults to the text "Sleep" with a right-pointing arrow for the flyout.  The only reason you "know" that that's where shutdown is is because that's where shutdown has been in Windows since Windows 95.  For Win8 I've set my power button on my PC to "Hibernate" which is crazy fast in Win8 compared to Win7, you can set this in "Power Options" and then it's just hitting the button on your PC and walking away.
