The Windows user interface has a certain archaeological quality to it. While the upper layers tend to be new—using the styling and conventions of the day—dig a little deeper and you can find elements that are decades old. With each Windows release, Microsoft has heaped new stuff onto the pile, but it hasn’t spent much time going back and revamping the old bits. Very occasionally, the relics of yesteryear are identified and excised, but more often than not, they’re left alone.

One area where this is particularly plain is Control Panel. Control Panel spans many eras of Windows development, and so Windows’ settings are spread across three different styles of interface. The very oldest are the individual Control Panel applets in their tabbed dialog boxes; more recent are the Explorer-based Control Panels. The very newest is the Settings app.

With Windows 10, the company has, for the first time ever, taken serious strides toward modernizing even old parts of the operating system. With each new update, more and more settings are being moved from Control Panel into the Settings app. This creates the possibility that perhaps one day Windows will have a single application that is used for all its major settings and configurations.
