What is %0| nd how does it work?

Question

If you run a .bat or .cmd file with %0|%0 inside, your computer starts to use a lot of memory and after several minutes, is restarted. Why does this code block

Answer 1

It's a logic bomb, it keeps recreating itself and takes up all your CPU resources. It overloads your computer with too many processes and it forces it to shut down. If you make a batch file with this in it and start it you can end it using taskmgr. You have to do this pretty quickly or your computer will be too slow to do anything.
