Thank you for the pointer to the wmi module. Is there a reference for
it? I just see the tutorial and cookbook. I installed it via
ActiveState's pypm, but it doesn't seem to have installed new
documentation in the help browser.
The wmi-based code also returned nothing. Then I realized my problem: I
did not choose "Run as Administrator" when I launched the pythonwin GUI.
When I did that, everything worked. I assume the code I tried would
also work in this mode.
In contrast, I had launched the command prompt as administrator, so that
was the environment cscript ran my VBS in. So that's why it worked, and
the python didn't.
