Actually, I follow this one pretty much, too. I've just been a bit busy
these last few days. And still am, so this answer will be short :)

1) I'm not sure if WMI can be forced to close down system processes,
but if it can it's probably by means of specifying one or more
privileges when you connect. Try looking in the WMI newsgroups
for a more general (non-Python) answer to this and I'll happily
explain how to apply it in a Python context.

2) I can't quite see from this traceback where the problem
arises. Have you snipped the traceback at all, or was that
all there was? Can you narrow the thing down to a short
snippet of code which I'm likely to be able to run independently,

Sorry for the haste.
