Cygwin doesn't need to use the registry.  It only does so when there are
actual entries.  It isn't required to have a root directory or a /bin
directory, etc.  The registry entries are either written by setup.exe or
mount.exe but neither is required.

If you're seeing this then you're running an older version of cygwin.  It's
possible that some of the registry "directories" might be created but there
should be no actual data.
