@Dr Herbie:1. People don't read this.  2. You can do this if you want (just create a shortcut to shutdown.exe with relevent parameters but TBH I don't understand the problem.

In Win7 Start handled shutdown applaunch and search, the "other stuff" (networking, volume etc etc) was in the system notification area.  In Win8, everything other than launching apps is in Settings. Brightness? Settings. Power? Settings.  Windows Update? Settings->PC Settings. Volume? Settings.  I don't see the power button in the settings panel as any less discoverable than an unlabelled arrow next to "Sleep" in Windows 7's unlabelled start orb.
