Nocturne uses a feature of Mac OSX to help with the screen inversion. It might be possible on windows but I've not seen it. You can actually screen invert on Macs without Nocturne using the universal access (accessibility ) preferences, but Nocturne smooths out the rough edges. Accessibility preferences on windows might also have this feature.
