The ability to perform tasks from a system’s command line allows those tasks to be used in batch files. This recipe describes several uses of taskkill to terminate Windows processes.
If you know the name of a process to kill, for example notepad.exe, use the following command from a command prompt to end it:
taskkill /IM notepad.exe
This will cause the program to terminate gracefully, asking for confirmation if there are unsaved changes. To forcefully kill the same process, add the /F option to the command line. Be careful with the /F option as it will terminate all matching processes without confirmation.
To kill a single instance of a process, specify its process id (PID). For example, if the desired process has a PID of 827, use the following command to kill it:
taskkill /PID 827
Using filters, a variety of different patterns can be used to specify the processes to kill. For example, the following filter syntax will forcefully kill all processes owned by the user Quinn:
taskkill /F /FI "USERNAME eq Quinn"
