Details of the registry entries are at http://msdn.microsoft.com/en-us/library/ms725481.aspx. It looks like the data is focused on modern timezones rather than localities, which would mean a many-to-one mapping from zoneinfo. Unfortunately it doesn't look like there's enough overlap to allow an automated mapping.
No, but the Unicode consortium (I think) is keeping a mapping updated manually. I'm using that in tzlocal, to figure out the local timezone of the computer on Windows. However, I think that mixing and matching timezone data in this way from the two systems are likely to be full of pitfalls edge-cases and complexities I do not dare even think seriously about. There will probably be less errors by just keeping an old timezone database around. Besides, what it they don't run Windows update? Then the data still is outdated?
