Just because it's inside an platform-ifdef doesn't mean it's not useful in a cross-platform application. That code would only be active when built on Windows and provide some optional functionality that probably isn't worth writing a cross-platform abstraction layer for (especially since this is accessing the Windows registry, which doesn't have an equivalent on other platforms).
