I’m surprised this is still a complaint, for two reasons. First, many major apps don’t bother having a native look and instead have their own skins. Second, Windows is such a mess that it no longer has an obvious standard look and feel anymore. This has been shown here recently screenshots. Microsoft’s own products, when not using custom skins, are using any of several “native” toolkits with their own aesthetics. None of them are particularly interesting so if it isn’t for consistency, there isn’t a strong reason to imitate any of them.
