Shutting Down Your PC
Many of these shutdown options are found on the official Shutdown menu, which you can access by clicking the triangle button in the lower-right corner of the Start button's menu (see this figure). For dealing with computer shutdown, here are your choices:
Keep the computer on all the time: This option is viable. Really, it is.
Log off: Tell Windows that you’re done without having to turn the computer off and then on again.
Lock the computer: Use this quick way to suspend computer operations and present the login screen, but without actually logging off.
Switch the user: Allow another user on the same computer to access their account without logging off from your own account.
Sleep mode: The computer slips into a special, power-saving Sleep mode, like going into a low-power coma.
Hibernate: The computer turns itself off, but when you turn it back on again, it comes back to life much faster that it does when restarting. Think suspended animation.
Restart: You turn the computer off and on again in one step, mainly when installing or upgrading software, or sometimes to fix minor quirks — like slapping Windows upside its head.
Shut down: Just turn the darn thing off.
Yank the power cord out of the wall: This method is satisfying, but not recommended.
