If you mean you would like to use Windows' timezone data, the answer is
you can't --- and you generally shouldn't want to, because AFAIK their
timezone data is pretty sucky: it's incomplete and not terribly accurate
about historical details. We use the IANA timezone database[1], which is
where those names like Asia/Calcutta come from.
Most modern operating systems use the IANA database for their system-level
timezone knowledge, but Windows is still in the dark ages last I heard.
