Shut-down The Computer After Conveying Any Message                            

This one is kind of an annoying trick and if used unknowingly can certainly cause problems (am serious). What this trick does is, after conveying a (any) message it shuts down the computer without any confirmation. In order to create the Shutdown file, follow the below mentioned steps:

• Open Notepad.
• Paste the following code in it:

shutdown -s -c "Error! You have to take rest! Byeeeeee" -t 20

Save the file with .bat extension like "anything.bat"
