Introduction: Funny, Easy Computer Pranks

Picture of Funny, Easy Computer Pranks

Hi everyone!
Here is a fun, funny, and easy way to annoy your friends and family members by (harmlessly) messing with their computers. This one is a simple batch file that makes a message box pop up that says anything you want. The trick: no matter how many times you click OK, the message will never go away! Have fun!

Step 1: The Batch File

Picture of The Batch File

1: Open notepad (under Start > All Programs > Accesories > Notepad
Copy and paste these lines into Notepad:

@echo off
msg * Insert your message here
goto top

Be sure to delete "insert your message here" and replace it with your own message!

Step 2: Saving the File

Go to File and click Save As.

First look at "Save as File Type" near the bottom. It should say "Text Documents". Change it to "All Files".

Type the name of your file into the "File Name" box, and be sure to end it with ".bat" instead of ".txt"

Save it to your "My Documents" folder.

Step 3: The Funny Part

Now, if you click on the batch file (which should look like a box with a gear inside it) in your Documents folder, the message should pop up. It will only go away if you restart the computer.

To make it begin automatically when you (or someone else) logs in, copy the file from the Documents folder.

Go to "My Computer", then go to:
Local Disk > Documents and Settings > (Username of Person you want to annoy) > Start Menu > Programs > Startup.

Paste the batch file  into the Startup folder.

Now it will run whenever they log in, and the person will never be able to find it! Mwahahaha!

Dusty2000 (author)2014-02-07

I respect your great prank tactic but...

you should make it:
@echo off
md C:\users\%username%\desktop\%random%
goto top
this will make BILLIONS of folders on the desktop
and by billions, i litterly mean billions

But I really wanted to do it to my brother for breaking my computer

saintjimmy (author)divaalert2013-05-24

Do you have Windows 7? It might not work with that, check out Undreamer's comment, it explains how to do it pretty well with Win7. Sorry, this Instructable was made a while back :)

divaalert (author)2013-05-24

It didn't work when I did it

saintjimmy (author)chydara2013-04-17

OK I e-mailed the file to you! :)

chydara (author)2013-04-16

hey can you send this through facebook? please reply!

saintjimmy (author)chydara2013-04-16

Sure... to preserve anonymity though, I'd rather e-mail it to you. Can you PM me your e-mail address?

All I have to say is that Undreamer's way is a lot easier to remember and works on school computers which is <(^-^)>.....

Ada22 (author)2012-03-24

it goes away though right?

i dont want to sound dumb but i'm not much of a computer whiz....

Ada22 (author)Ada222012-03-24

oh wait nvm. it goes away with restarting ur computer.... (right?!)

saintjimmy (author)Ada222012-03-24

Yup, it will definitely go away if you restart the computer. You can also go into task manager (press Ctr Alt Delete), and end the program there. It will probably go away after a while if you do that, but you'll have to click it a few times. This might not work, it just does on my computer, but restarting the computer will always work.

Thanks for commenting!

Ada22 (author)saintjimmy2012-04-02

ok thanks for clearing that up. Cant wait to try it on my parents computer :D

someguyfromUK (author)2012-03-05

Can you send the file as an email? I want to get my dad but he's on it too often so i can't do it directly. Please reply, this is my first EVER comment

saintjimmy (author)someguyfromUK2012-03-10

OK, I e-mailed the file to you... just figured I'd tell you here in case you don't check your old e-mail :)

saintjimmy (author)someguyfromUK2012-03-05

I would be happy to! Just tell me your e-mail, or I could upload it to this Instructable... Whichever one suits you! Also, if you want another computer prank to play on your dad, check out my other Instructable for a "psychic" computer application. I could e-mail you that one too if you want.

someguyfromUK (author)saintjimmy2012-03-06

ok just send it to this email adress is one i had from when i was seven but the only one that doesn't show my name... Thanks

Undreamer (author)2012-02-09

just came across this instructable looks nice but unfortunately doesnt work on windows 7.
however you can achieve same result if you write inside your file:

msgbox " Insert your message here"

and save it with ' .vbs ' extension.

saintjimmy (author)Undreamer2012-02-09

Thanks for posting that, I've never tried it with Windows 7 before! Wondering, though, what does the ".vbs" stand for? Does this have anything to do with BASIC?

Undreamer (author)saintjimmy2012-02-09

stands for Visual Basic Script
uses visual basic interpreter, though im not sure if you gotta
have anything installed to use it...
however i did check it on XP with only office 2003 installed and it worked...

saintjimmy (author)Undreamer2012-02-10

Hmm, I'm surprised they did away with the .bat file in Win7, but I just thought it was funny because I just installed the Visual Basic program (for free) and I wanted to post an Instructable on how to make a little game with that. Anyhow, thanks again for the answering my question!
