If you spawn the processes yourself from within a perl script you should use Win32::Job . This will give you job control and thus the ability to kill a group of process.

As i understand it, this is the way to control processes in Windows, that is killing a processes and all itīs sons.

I find dealing with PID and PPIDS is kind of not adapted since PIDs numbers are recycled fastly and you could kill something else !

In "real" windows programing there may be something like a "process handle" that you get when you create a process and that allow fine control, but within Perl Win32::Job seems the way to go ...
