Introduction: !!GREAT COMPUTER PRANKS !! Computer Commands Using Notepad and Command Prompt

In this Instructable i will show you how to make a few pranks on peoples computer using simple commands on notepad and cmd prompt.

I MADE THIS INSTRUCTABLE TO ENTER THE APRIL FOOLS SPEED CONTEST SO PLEASE VOTE BY HITTING THE VOTE BUTTON AT THE TOP

Step 1: Fake Warning Message

Ok first we will start with the easy one, the fake warning message.
This is how to do it:
1.Open note pad
2.Type this in
@echo off
msg * Warning your computer has detected a virus.
msg * To remove the virus click OK or close this box
msg * Your Hard drives are now being formatted
msg * Please wait ...........
msg * APRIL FOOLS

3.Save the file as April-fools.BAT
4.Right click on the file and press hidden
5.Go to folder options and click show hidden files
6.Cut the file and place it in the victims Start up folder in the start menu
7.Go back to folder options and click do not show hidden files.

Now what each of the lines you typed in done:
@echo off << this runs the commands in the background so the victim will not see any codes
msg * <<this commands the computer to show a message
msg * hahahah <<this is what the message will display

The results
when the victim starts up there computer the first message will appear, when they click OK the next one will appear and make the victim think there hard drive is being formatted until they get the last message saying APRIL FOOLS.

Now your code should look like the image below:

Step 2: Fake Icon

Now i am going to tell you how to make fake icons that will shutdown/ log off / restart the victims computer.

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.
2.Select new.
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

Step 3: A Simple Older Prank

Ok this only works on people that are not very smart with computers.

This will make them think their computer has froze and (if they are not smart with computers) they will freak out.
1.Close all open programs
2.Make sure you can see everything in the desktop
3.press print screen
4.Open MS paint and right click and press paste
5.save the file in some where you can easily find it
6.Go back to the desktop and right click, select arrange icons and click hide icons
7.Right click on the start bar and click properties and click Auto-hide
8.Goto the desktop and right click, select properties and click the desktop tab
9.Click load background and find the file you saved.

RESULTS
Now the computer should look normal but you cannot click any icons or the start bar as they are just an image. To do this sneak onto a friends / school computer and it only takes 2 minutes!

Step 4: Fork Bomb (BATCH)

This prank will make a command run over and over until the computer cannot handle any more programs and the computer will freeze or shutdown.
!!!!THIS IS HARMLESS AND WILL DO NO DAMAGE TO YOUR COMPUTER!!!!!

To make this open note pad and type:

@echo off
:START
start a.bat
GOTO START

The code above must be saved as a.bat and when the other person opens it nothing will appear but in the background it will keep opening its self until the computer freezes or shuts down.

Step 5: Fake Virus Detected(HARMLESS)

Ok this will make the victim think they have got a virus when they click on an icon such as my computer.
First we have to open notepad again
1.type this in or copy.
@echo off
echo WARNING VIRUS DETECTED
echo System check
echo -
echo Hard drive - FAILED
echo -
echo RAM - FAILED
echo -
echo Disk Drive - FAILED
echo -
echo Connection - FAILED
echo -
echo code 754*sd56625
echo -
echo Hard drive must be formatted to resume windows
echo -
PAUSE

echo -WARNING

echo Hard drive has been formatted
echo -
echo -WARNING

echo APRIL FOOLS
echo APRIL FOOLS
echo APRIL FOOLS
echo APRIL FOOLS
echo APRIL FOOLS
echo APRIL FOOLS
echo APRIL FOOLS
echo APRIL FOOLS
echo APRIL FOOLS
echo APRIL FOOLS
pause

2.Save as a.bat
3.convert the a.bat to an exe file which lets you name it and change the icon.
4.to convert it you will need to goto www.f2ko.de and download bat_to_exe
5. put it on some ones computer and watch them freak out

RESULTS
Look at the screen shot below and this is what the person will see. where it says pause you have to press a key to see the writing below it.

P.S WHEN YOU ARE CONVERTING THE BAT FILE TO EXE USE ONLY THE TOP 4 BOXES IN THE CONVERTER
