My personal "how-to-quit-it" challenge was Windows 8. I tried to approach it from the perspective of someone who has previously used Windows but is not a power user knowing shortcuts like Alt + F4 or Ctrl + Alt + Del. In the first Windows 8 versions, it was not obvious at all how to turn off the computer. The classic start menu was gone. The start menu button had no context menu, as far as I can remember. There was no obvious button in the "new" full-screen start menu. I tried quite a few places, I think in the end it took me close to ten minutes to figure out that I had to click on the user profile picture in the new start menu to reach the shutdown option, or something like that. It really was all but obvious. In later updates they improved it a bit.
