Automatically Kill Programs At Shutdown

I hate it when I'm trying to shut down my windows XP and i get that annoying pop up telling me that programs are still running, so I found a way to make windows automatically kill/end the running programs on shutdown. Just open regedit by going to start>run and typing regedit and navigating to HKEY_CURRENT_USER>Control Panel>Desktop directory in the Registry, and then right click on AutoEndTasks and select modify binary data, then change the value to 1.
