One problem is that there is no one Windows style. The style guidelines, if you can call them that, depend on a few things like age and provenance of the component (some examples of pieces with distinct styles: filesystem, registry, GDI, NT API, COM). And sometimes you see a mix of these, or a component come along with its own variation. (SDDL and other security APIs is a good example of a unique style.) But sometimes people confuse unfamiliarity with ugliness, being bad or wrong, and having worked with a lot of these stuff I feel this is often a mischaracterization. Unfamiliarity doesn't always make it bad.
