Killing a process and all its children processes....
Hi
Doing a newsgroup search with http://groups.google.com/advanced_group_search
the following came up that makes it look like that the answer to your question
is no:

Subject: Re: "bWaitOnReturn" option for WshShell.Run method

"...Is there a way of tracking which processes are spawned by other processes.
..."
If you know that foo.exe will spawn an instance of bar.exe, you *could* use
WMI it track the PIDs
(Process IDs) of instances of bar.exe. For example, before executing foo.exe,
record the PIDs (if
any) of bar.exe instances. Execute foo.exe and recheck the PIDs for bar.exe
instances. The one
that is new is for the new instance of bar.exe spawned by foo.exe. There
might even be a more
direct way using WMI notification events but that would take a lot more time
to research ;-)...
I don't know if there is a generic technique available to script clients to
track the child
processes of an arbitrary parent process. If there is one it would probably
involve WMI...
