How to kill a running program (not in task manager).

I started an instance of robocopy.exe in a dos batch file, using the task scheduler. It tries to copy a large backup file to a network share.
I then attempted to stop the process by choosing "End Task" in the task scheduler.
The task stopped, but apparently robocopy continues to run in the background. Any time the share is available, the computer copies data to it. I can't stop it. Running SIW (System Information for Windows by Gabriel Topala), shows robocopy running, and open files by robocopy. Rebooting the server did not stop the process. How do I  kill it?

Here is what I have:
Process running shown by SIW:

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

There are a couple of tools available but I personally prefer pskill since it can terminate local and remote processes.
Robo copy must install as a service then go into services then disable the service

Hi HilltownHealthCenter,

Windows have built in utility to kill processes caled TASKKILL. The only thing you have to specify is PID of a process you want to kill:

"Taskkill /PID 123"

I found "tasklist" to list PIDs.
