I don't remember where, but I once read that all the developers that knew and understood the inner workings of core Windows components have left Microsoft many years ago, and that this is part of the reason that they introduced a brand new Settings menu and haven't changed Control Panel since Windows 7. I don't know how reliable that report is so take it with a grain of salt, but it does make a lot of sense considering what's been happening to Windows over the past 10 years.
