How to kill only background process?

Question

cmd/bat

The problem is of the following nature, several program.exe are running, when one of the processes shuts down for some time, it still "hangs" in the background and does something (sometimes for a very long time).
It is necessary to terminate this particular process, which has become background, from the command line, the rest should continue to work.
Upd: Everything should happen automatically, processes work on servers (batch file is looped)

you need to know his PID and kill by PID

Answer 2

In the task manager, add the "PID" column, fix the process number. Further from the command line "taskkill / pid process_id".
