PYTHONPATH on the Windows Registry?

[Ixokai]

    Question-- if Python on Windows (w/o win32all) is running on a machine,
without any PYTHONPATH/etc set in the registry, but with an environment
variable set, will it set its 'current' python path into the registry? Or
set anything at all? I want a zero-impact run of Python on the system. :)

Thanks.
