Shutdown Your PC using CMD

This might not seem necessary since the power button is tucked neatly inside the Start Menu, but this trick has a few more uses. Not only can you use this on your machine, but on network machines as well – as long as you have administrative access! You can also restart machines, set comments (the reason for the shutdown), specify time and more!








List Of Shutdown Command Switches

No Switches	Display information about the shutdown command, same as typing “-?”
-i	Display a GUI. It must be the first switch
-l	Log off the user (This cannot be used on a remote machine: “-m” switch)
-s	Shutdown the computer
-r	Restart the computer
-a	Cancels a system shutdown already in progress
-f	Forces running applications to close without warning
-m \\computername	Instruct a remote computer to shutdown (can be used with the restart & abort switches)
-t xx	Set a given time for shutdown, in seconds
-c “comment”	Shutdown comment (maximum of 127 characters)
-d [u] [p]:xx:yy	The reason code for the shutdown: u is the user code p is a planned shutdown code xx is the major reason code (positive integer less than 256) yy is the minor reason code (positive integer less than 65536)

Shutdown Local Machine
This only takes a couple of keystrokes. Type the code below and hit OK:

shutdown -s

“shutdown” tells the computer what command we want to execute and the “-s” switch tells it what to do, which is to shutdown!

Specify Time

shutdown -s -t 60

Now we have added the “-t” switch and a variable, which in this case is “60″. This number is the number of seconds before the computer is shutdown. A dialog will open and display a count down timer!

Shutdown with Some Info!

shutdown -s -t 120 -c "You better finish, because I shut you down foo!"

The “-c” switch will allow you to give the user some information for the reason of the shutdown.

Shutdown A Remote Computer

shutdown -s -m \\desktop -t 45

I really like this one! The “-m” switch will allow you to shutdown a remote machine, in this case, a computer named “desktop”. For this to work, you must have administrative access to the computer! To see of you do, hit Windows Key + R then type the computer’s name

Cancel Shutdown
Let’s say that you need to cancel a shutdown in progress. Go to the computer in question, hit Windows Key + R then type command below:

shutdown -a

This will abort the shutdown, assuming there is a counter and it hasn’t reached zero yet!
