How Shutdown and Reboot Remote Computer Via Email and Simple Bat File

During your busy life, there may be circumstances where you forgot to turn off our desktop computer or laptop at home or office. A running computer consuming the increasingly valuable electricity is a waste of energy. You may go back to the computer and shut it down manually if you’re not in a rush, but what if you got a plane to catch up or you’re already miles away from the computer? Well,  it can be quite annoying.

In this article, I will explain quick tips on how to use a simple command prompt (batch Windows file) and send it via email to turn off or reboot a remote computer. You can use the reboot or shutdown instructions regardless of operating systems you’re using, without having to know the IP address of the target PC. The bat files work with either older versions of Windows such as Windows XP, Windows Vista or earlier Microsoft Windows versions.

Keep in mind, you need to create the command files in advance and put them somewhere on your computer folders before being able to shut down or restart it remotely.

A. Send Remote Restart/Shutdown Using Outlook

Without further ado, here is a step-by-step guide to shutdown/restart remote computers using simple bat file sent via email

A.1 STEP ONE: Create the bat file

Create a bat file by opening notepad and type the following command line and then save on your computer with any name. Don’t forget to append it with .bat extension and use Save as in all file options dialog box, example: shutdown.bat

The Shutdown command:

C:\WINDOWS\system32\shutdown.exe -s -f -t 00

The Restart Command:

C:\WINDOWS\system32\shutdown.exe -r -f -t 00

Note:

The above command lines will force close all running applications on the computer.Make sure you don’t have unsaved data on your computer before executing the files.

Save the newly-created bat file somewhere on your computer or put it as a shortcut in Windows desktop. To avoid cluttering your desktop with shortcuts you may want to put the file in the following folder:

C:\Documents and Settings\Administrator folder
