It seems that this person wants a method to terminate a task that was not created by Win32::Process::Create. Win32::Process does not seem to allow control of such processes (at least not in the exported methods). I have done some research today looking for a module that might allow it, but other than resorting to a Win32API system call, I cannot find one.

Update: I have refreshed my memory on Win32 system calls, and it does not appear to be possible to use an API call to kill a window unless the killer spawned the process. It is quite possible that there is something that I don't know about that will do this, as I am by no means a Win32 guru, but it looks to me like it is not ... or it's very difficult.
