Would taskkill.exe help?

For example, "taskkill.exe /im dumpcap.exe" , etc.

I've also used WMIC in the past to save ProcessID's of tasks so you can later kill specific instances of a task instead of all of them with the same name.  I'd refer you to the dumpcap.bat file posted on https://wiki.wireshark.org/Tools for how I did that.
