More and more people are installing recently released Windows 8 RTM and all are asking same question. How to restart, log off or shut down Windows 8 computer?
Actually Microsoft has removed Start button and Start Menu from Windows 8 and that's why you can't select restart, shut down, etc options from there. (You can enable the Start button and Start menu in Windows 8 using this tutorial.)
The new Start Screen also doesn't provide any direct shortcut to restart or shut down the PC, then how to turn your system off?
Don't worry! Although there are no direct options given in Windows 8 but here in this tutorial we are going to share lots of ways to lock, log off, restart and shut down your Windows 8 PC:
METHOD 1: Using Ctrl+Alt+Del Key Combination
It doesn't matter whether you are on new Start Screen or Windows 8 Desktop, simply press the good old Ctrl+Alt+Del key combination and it'll show following screen:

Now you can lock, log off or switch between users. If you want to restart or shut down your system, click on the turn off icon given at the bottom-right corner and select the desired option.
METHOD 2: Using New Charms Bar
Again this method works for both Start Screen and Desktop. Simply move your mouse cursor at the extreme top-right corner and it'll show the new Charms bar. Click on "Settings" charm and it'll show a sidebar in right-side of screen.

There you can click on "Power" button and select the desired option.
METHOD 3: Using Alt+F4 Key Combination
This method only works for Desktop. Click on Taskbar and press Alt+F4 keys together. It'll show following dialog box:

Now you can select the desired option from drop-down menu and click on OK button.
METHOD 4: Using User Details Shown at Start Screen
This method only works for Start Screen. It allows you to lock or log off in Windows 8.
Simply click on your username or avatar shown at the top-right corner of Start Screen and there you can select the desired option:

That's it. These all are the easiest and quickest ways to log off, restart and shut down a Windows 8 PC. Please feel free to share more ways if you know in your comment...

"That's it. These all are the easiest and quickest ways to log off, restart and shut down a Windows 8 PC."
REALLY?!? YHGTBSM!!!
How about you try this?
Tap the POWER button.
No clicks, no screens, no ALT keys, just the most straightforward shut down ever.
Just like in the IBM XT days. When we loaded our OS off of 5.25" floppies and liked it! Gimme an A:! ....

This is way too complicated. When do you plan to publish a User Manual?

The shutdown -l command worked like a charm.
Just created a shortcut and docked it on the task bar, now log off is right there.

Hello,
I've got another slight incovenience. In shutdown dialog box (in Alt + F4 option) I cannot rearrange the order of commands. I want to have "Shut down" as the first option (currently it is "Switch user"). How could I tweak it up to my taste?
