Hi Sid,

As you are trying to work with some code of mine that is broken on
non-English systems, I figured I should do my bit :)
Below is a port of that KB article to Python. If cvs on sourceforge wasn't
giving me trouble, it would already be checked in as
win32\Demos\security\localized_names.py
Cheers,
Mark.
