Can anyone recommend an application (preferably usb-portable that doesn't require setup) That really kills a process immediately in windows XP?

I ask this because often when I need to use the XP task manager it seems to want to go about it "the polite way" and sometimes crashed programs don't quit or take a minute to shut down.

I need a real stone cold killer, not a pushover-could-you-please-quit-now-no?-ok-sorry-program

Edit I'm sorry if it wasn't clear previously but I did mean the situation when even the "End process" command in Process tab of the task manager doesn't kill a program, however one of the answers did point me to the "End Process Tree" command which I've never noticed (when right clicking on the process)

If normal Task Manager fails you can get Sysinternals Process Explorer. It allows you to kill services too so it's a lot better then standard TaskMgr. This is useful in case some service has hung that even stop/restart doesn't work on it.

I usually will use the "End Process Tree" option in the Processes tab of the Task Manager. I find this method to kill the problem much faster and with better results that just using "End Process" by itself.

Nice, didn't know about that one – Moak Mar 2 '11 at 13:27
This is only available from the context menu, whereas the basic "End Process" option has a button as well. – ChrisF Mar 2 '11 at 14:38

Using the End Process option on the Processes tab of the Task Manager is (or at least should be) a sure fire way of terminating an application.

The only problem you might have is that if an application starts several processes you need to find and kill the "master" process to ensure that it all stops in one go.

When "End Process" is not working, program has crashed in a way it can't be terminated (without reboot). There is no magical process killer application that's going to help in that case. – Olli Mar 2 '11 at 12:59
@Olli - hence the "or at least should be" part :) – ChrisF Mar 2 '11 at 13:02
yes, I was just predicting that there will be comments saying "No, I had case when it didn't work. I want better program" – Olli Mar 2 '11 at 13:03

Process Explorer has this functionality.

Use Wixkill. It kills bothering apps on your system just like xkill in Linux does. Here is an improved version. It's free and portable (just 17.9 KB).
