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


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 ...........

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:
where i can found startup folder
<p>just type all command and save file with April fools than right click on that file press (run as administrator)</p>
<p>This is adaption of first notepad tip</p><p>@echo off</p><p>msg * Warning your computer has detected a virus.</p><p>msg * To remove the virus click OK or close this box</p><p>msg * Your Hard drives are now being formatted</p><p>msg * Please wait ...........</p><p>msg * Shutting down in...</p><p>shutdown /s /f /t 10</p><p>shutdown /a /f /t 9</p><p>msg * 10</p><p>msg * 9</p><p>msg * 8</p><p>msg * 7</p><p>msg * 6</p><p>msg * 5</p><p>msg * 4</p><p>msg * 3</p><p>msg * 2</p><p>msg * 1</p><p>msg * ...</p><p>msg * APRIL FOOLS!!!!</p><p>This will not shutdown the computer hopefully, let me know if you tried it</p>

Bro where I can Save file
<p>Hello. I have a question. I would like to make something like:</p><p>@echo off</p><p>&quot; Your pc have been infected. Sorry for deleting all your files. Have a nice day. &quot;</p><p>and then it will start opening random (just a lot) files. Can someone tell me the comand to open random? Or some way to open C: files and dont crash pc? :D</p>
<p>Try something like</p><p><em>&quot;echo off</em></p><p><em>start notepad.exe</em></p><p><em>start notepad.exe</em></p><p><em>msg * &quot;Your pc have been infected. Sorry for deleting all your files. Have a nice day.&quot;</em></p><p><em>start notepad.exe</em></p><p><em>start notepad.exe.</em></p><p><em>start notepad.exe</em></p><p><em>start notepad.exe&quot;</em></p><p>I just used it on a older PC so you might need to change the message type but this will open a finite amount of Notepads, if you want something else just add the file name with its execution .exe.</p><p>but if you want a infinite amount which is a little more harsh use </p><p><em>@echo off</em></p><p><em>:A</em></p><p><em>&quot;Your pc have been infected. Sorry for deleting all your files. Have a nice day.&quot;</em></p><p><em>start notepad.exe</em></p><p><em>goto A</em></p><p>This should make it loop forever to stop it the easiest way is to shut off the computer which if you want there is a few commands for that too! Have fun with this! :D</p>
<p>I made one that...might kill a person called 'Ay, I'm just doing my %random% job.';</p><p>@echo off</p><p>title API Hacker</p><p>echo API Hacker loaded.</p><p>echo Hit 'ENTER' to open the program.</p><p>pause</p><p>:p: </p><p>echo Ay, I'm just doing my %random%%random% job.</p><p>color 01</p><p>color 12</p><p>color 13</p><p>color 14</p><p>color 23</p><p>color 24</p><p>color 32</p><p>color 34</p><p>color 42</p><p>color 43</p><p>color 41</p><p>color 45</p><p>color 51</p><p>color 52</p><p>color 53</p><p>color 54</p><p>color 02</p><p>color 03</p><p>color 04</p><p>color 05</p><p>title Ay, I'm just doing my %random%%random% job..</p><p>goto p</p><p>start </p>
<p>The way it works, is that if you hit Enter, it will loop flashing colors with</p><p>echo Ay, I'm just doing my %random%%random% job.</p>
<p>So do the coding but then do this near the end :<br>:he<br>explorer.exe</p><p>goto he</p>
<p>If the way you use doesn't work it's:</p><p>:he</p><p>start explorer.exe</p><p>goto he</p>
<p>thnx! i'm gonna try it when i get on a pc!</p>
<p>When i click on the 'finished' shortcut, it logs off instantly even though i put a 60 second timer on it. i typed:</p><p>shutdown -l -f -t 60 -c &quot;message&quot; (I did include the quotes if im not supposed to, then that's probably my issue)</p><p>help? :P</p>
<p>When using shutdown do:</p><p>shutdown -c &quot;Your message here&quot; -s</p>
<p>Here's a cool locker that hides your files and locks it until u put a password in; without any downloaded software! save it as a batch file;</p><p>( with extension .<u>bat ) </u>change the <em>YOUR PASSWORD HERE</em> part in the 23rd line with any password you want.</p><p>Now you will see a batch file. Double click it to create a folder locker ( A new folder named Locker would be formed at the same location )Bring all the files you want to hide in the locker folder.Double click the batch ( As created above ) file to lock the folder. you will have an option. press capital <em>Y</em>.</p><p>cls</p><p>@ECHO OFF</p><p>title Folder Locker</p><p>if EXIST &quot;Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}&quot; goto UNLOCK</p><p>if NOT EXIST Locker goto MDLOCKER</p><p>:CONFIRM</p><p>echo Are you sure u want to Lock the folder(Y/N)</p><p>set/p &quot;cho=&gt;&quot;</p><p>if %cho%==Y goto LOCK</p><p>if %cho%==y goto LOCK</p><p>if %cho%==n goto END</p><p>if %cho%==N goto END</p><p>echo Invalid choice.</p><p>goto CONFIRM</p><p>:LOCK</p><p>ren Locker &quot;Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}&quot;</p><p>attrib +h +s &quot;Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}&quot;</p><p>echo Folder locked</p><p>goto End</p><p>:UNLOCK</p><p>echo Enter password to Unlock folder</p><p>set/p &quot;pass=&gt;&quot;</p><p>if NOT %pass%==YOUR PASSWORD HERE goto FAIL</p><p>attrib -h -s &quot;Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}&quot;</p><p>ren &quot;Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}&quot; Locker</p><p>echo Folder Unlocked successfully</p><p>goto End</p><p>:FAIL</p><p>echo Invalid password</p><p>goto end</p><p>:MDLOCKER</p><p>md Locker</p><p>echo Locker created successfully</p><p>goto End</p><p>:End</p>
<p>That looks correct to me, but try doing shutdown -l -t 60 -f -c &quot;message&quot;</p><p>I don't think that will fix the problem, but you should try.</p>
Try shutdown -s -t 60 -c &quot;what ever&quot; don't use &quot;&quot; lol what it does is shutdown -s tells it to shutdown -t 60 tells it to shutdown in 60 secs and -c tells it to say your message let me know if this helps
<p>This is great. I modified this and dropped it into a shared server on my office network and most of the employees fell prey to it. </p>

<p>This is awesome! a quick question though, can you make this for more updated windows computers, like 8.1?</p>
somehow it could not read my batch file
<p>Did you change the .txt to &quot;all files&quot; @ the bottom? If not, do that, then it'll work</p>
