Opening/Closing application via .bat file [Windows]

TASKKILL /IM asperascp.exe /F
will kill all images with the same image name. So if you run the same program twice, for example, and the second one starts before the first one exits, the second one will be killed too when the first one runs taskkill. If you do tasklist you will see some images with the same image name, but with differing PIDs. You will have to get the PID of the process started by your batch file (I can't think of how to do this with CMD.) Then you can use: TASKKILL /PID 999 /F

You can use Start /b command.
