Step 2: Fake icon
When you make this use a 60 or more second time limit so the user has time to save all open work as if you do not it may make them angry and not so much a prank but with a time limit they have nothing to lose and will find it funny after.
There is two ways to do this but the way i am going to show you is easiest:
How to do it:
1.Right click on the desktop in a blank space.
3.Click where it says create shortcut
4.Where it tells you to type a location type in one of the codes below:
If you want there computer to shutdown type this in:
shutdown -s -f -t 60 -c "type a message you want to appear here"
If you want it to log them off type this:
shutdown -l -f -t 60 -c "type a message you want to appear here"
If you want it to restart there computer type this:
shutdown -r -f -t 60 -c "type a message you want to appear here"
5.Click OK and name it My Computer.
6.Right click on the file you just made and click properties and look for where it says change icon.
7.find the icon that is the same as the "my computer" icon
8.change the icon and wait for the victim to open my computer, then it will shutdown / log off / restart.
9.HINT: If you set the time limit to 0000 it will shutdown instantly, so they may think it was some els wrong with the computer and try again .......
What each part of the code does:
shutdown << this is a program that has three basic commands shutdown , log off , restart.
-s << this will shutdown the computer
-r << this will restart the computer
-l << this will log off the computer
-f << this forces all programs running to shutdown
-t << this is the time limit until shutdown (the time is in seconds so if -t 60 means 60 seconds )
P.S if you want to try this on your computer and the shutdown timer starts, to stop it in run type shutdown -a
