Recent versions of LW are supposedly fitted with the ability to automatically transfer new songs onto iTunes (if the user chooses that option in the Preferences/Options), even for Windows users.
You still have to do all of the above to transfer previous songs in the Library, but subsequent songs should automatically transfer in a new iTunes playlist called Limewire.
