Shut Down or Restart Another Computer via cmd prompt
System administrators in a business environment do this all the time for lots of reasons, but you can also shut down or restart another computer on your network, all from your computer's Command Prompt.
The easiest way to shut down a computer remotely is to execute shutdown /i from the Command Prompt which will open the Remote Shutdown Dialog, shown here.
Just enter the name of the remote computer (which you can get by running the hostname command on the other PC), choose what you want to do (restart or shutdown), select some other options and then click OK.
So whether you're brushing up on your command skills or just scaring a family member, this Command Prompt trick is a fun one.
You can also shut down or restart another computer strictly from the Command Prompt with the shutdown command, without using the Remote Shutdown Dialog.
