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 your Windows? And what does this code programmatically do? Could it be considered a "bug"?

command-line
This is the Windows version of a fork bomb.
%0 is the name of the currently executing batch file. A batch file that contains just this line:
%0|%0
Is going to recursively execute itself forever, quickly creating many processes and slowing the system down.
This is not a bug in windows, it is just a very stupid thing to do in a batch file.
