Question

I am writing using JavaScript. I have a PID of a process. How do I kill it?
You can terminate by a name using WMI, How can you do it using PID?

UPDATE: The platform is Windows.

It looks like you’re coding for either Windows Script Host or a Windows Desktop Gadget. If it is, I would use WScript.Shell and its Exec method along with the command line taskkill (Win XP Pro, Win Vista & Win 7 only):

var WshShell = new ActiveXObject("WScript.Shell");
var oExec = WshShell.Exec("taskkill /pid 1234");

If you really want to do it with WMI something like the following works fine for me (thanks @Helen for the improvements):

function killPID (pid) {
  GetObject("winmgmts:").Get("Win32_Process.Handle='" + pid + "'").Terminate();
}
