Allow Windows images of any name to be valid

There is a use case where you may want/need multiple Windows versions with
different setups, but to still be one of the 6 currently allowed O/S.

This change is also useful if in a specific use case the Windows build was
dated with the date of build/last Windows Update baked in to it.

If one of the previously allowed 6 names are used for the Windows image, it
will still correctly give the title as expected, otherwise return the release
name.
