localsch.exe shows no task with /tasks

I run

localsch.exe /exe=exe-that-does-not-exist.exe

Now I'd like to remove the task running.

In the log :

Wed, 22 Aug 2012 15:52:24 2768 3932 Starting process: exe-that-does-not-exist.exe

Wed, 22 Aug 2012 15:52:24 2768 3932 failed to launch "exe-that-does-not-exist.exe "

Wed, 22 Aug 2012 15:54:24 2768 3932 failed to launch "exe-that-does-not-exist.exe "

But when I run localsch.exe /tasks, it displays nothing !!!

How is it possible ?

How can I find the taskid of my bad task ?

Thanks in advance.
