How do you shutdown a computer using command prompt?

To shut down a computer in command prompt first you have to pull it up- by going into "run" in te start menu and typing in "cmd". Then, when its open type in "shutdown" and a shutdown dialog will appear. When all the options for shutdown procedures show up, like "shutdown -m" and "shutdown -l" Type in "shutdown -i". When you enter this a remote shutdown dialog will appear on the screen. When it appears uncheck the two boxes and type in your computer name. (the computer name is under the control panel in "system propreties." Then enter it and your computer will shutdown.
