MiKTeX Console is meant to replace old MFC applications

MiKTeX Console is now the tool of choice for most MiKTeX maintenance tasks. The classic MiKTeX desktop applications (Settings, Package Manager, Update Wizard) are considered deprecated and will be removed in the future.

More info: MiKTeX desktop applications were originally implemented on top of the Microsoft Foundation Class (MFC) library, a framework for developing desktop applications for Windows. In the course of porting MiKTeX to Mac and Linux, it was necessary to rewrite the three applications.
