[python-win32] How do I change the executable/process name to un-group taskbar icons?

[Nathan McCorkle]

I've been writing GUIs with wxPython for a while now, and am trying to
figure out now how to get each program not to group into a generic
'pythonw' taskbar icon.

I found this API, but it doesn't work on my version of Windows XP:
SetCurrentProcessExplicitAppUserModelID

Is there some other method to change things?

Thanks!
