You can access a menu in Windows 8 that gives you access to all sorts of system-related things by bringing the cursor to the start menu hotspot (bottom-left corner of the screen) and right-clicking.
It looks like you can get to it pretty much any time except for while in a full-screen desktop app (like games) which seem to have quite a few problems for people not familiar with hotkeys.
