Well... I know a way to call the Blue Screen of Death (Windows' blue screen with an error on it, guess you've all seen it), it doesn't provide any names like shutting down does, so it can be done in class without any worries, so here is how it's done:
1. Start -> Run -> Write cmd or command and press Enter.
2. Write \\PC-NAME\Folder\CON\CON and press Enter. (or it can be written in the Run window)
Where:
- PC-NAME is the remote PC you want cause this screen to appear.
- Folder a shared folder on that computer
But there's one but: it might not work in Windows 2000 and later versions.
You can try something interesting too, every version of Windows has a file called autoexec.bat on the system drive (C: usually), by adding a couple of lines in it, you can prevent others from running Windows unless they press Ctrl + C (batch break command), here are those lines, add them in the begining, I'll comment each one after the '#':
@echo off #turns off message displaying, unless you write echo message to display the message
:loop #creates a label, will be used later
echo Error: Fatal system error (code: 0x00fb43) #displays the error message (you can use this one, I didn't copyright it ;-) )
pause #pauses and asks for a key to be pressed
goto loop #goes back to the loop label
You only need to add the text marked with bold, enjoy! And remember, only Ctrl + C can stop it, so it can be used as some sort of password to prevent "wrong" people from using the computer.
