Problem with Killing windows explorer?

Question

I need to kill windows explorer's process (explorer.exe), for that

lets say i use a native NT method TerminateProcess

It works but the problem is that the explorer starts again, may be windows is doing that, anyway. When i kill explorer.exe with windows task manager, it doesn't come back, its stays killed.

I want to do whatever taskmanager is doing through my application.

Edit:
Thanks to @sblom i solved it, a quick tweak in the registry did the trick. Although its a clever hack, apparently taskmnager has a cleaner way of doing that, that said, i've decided to go with @sblom's way for now.

From Technet:

You can set the registry key HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\AutoRestartShell to 0, and it will no longer auto-restart.
