You're working on the plane, feverishly trying to finish that PowerPoint presentation when the flight attendant tells you to completely power off your laptop right away. What do you do? If you're on Windows 8 and you know where to find the hidden option, you have to take take four steps: launch the charms menu, click the settings button, click the power button and then click "Shut down."
Windows 8.1 doesn't do anything to make the shut down function easier to find. However, it does have a second hidden shutdown option that's also several clicks away and appears when you go to the desktop, right click the start button and select Shut down from the Shut down menu (yes that's shutdown twice).
