Parameters

/s   Computer   : Specifies the name or IP address of a remote computer (do not use backslashes). The default is the local computer.

/u   Domain \ User   : Runs the command with the account permissions of the user specified by User or Domain\User. The default is the permissions of the current logged on user on the computer issuing the command.

/pid   ProcessID   : Specifies the process ID of the process to be terminated.

/im   ImageName   : Specifies the image name of the process to be terminated. Use the wildcard (*) to specify all image names.

/f   : Specifies that process(es) be forcefully terminated. This parameter is ignored for remote processes; all remote processes are forcefully terminated.

/t   : Specifies to terminate all child processes along with the parent process, commonly known as a tree kill.

/? : Displays help at the command prompt.

Remarks

  • The wildcard character (*) is accepted only when specified along with the filters.

  • Termination for remote processes will always be done forcefully regardless of whether the /f parameter is specified.

  • Supplying a computer name to the HOSTNAME filter will cause a shutdown and all processes will be stopped.

  • Use tasklist to determine the Process ID (PID) for the process to be terminated.

  • Taskkill is a replacement for the Kill tool.
