"Services" and "Disk Management" UI's are great examples of ollllld (possibly MFC?) Windows UI's and are still the standard way to manage those settings from what I can tell.
You can use Spy++ to look at the properties of open windows on your system. If the window class name starts with "afx:" then the application uses MFC. As far as I can recall I've never seen a Microsoft product built on either MFC or Visual Basic. They apparently don't like their own dog food.
They tried doing stuff in .Net for Vista but had to revert all that; perhaps they've now come back to using it for real, but I know the new settings panel is done in C/C++.
What's funny is I remember when those Microsoft Management Console snap-in tools were brand new, and what came before them was a lot less nice to use.
(They might be MFC. Windows 2000 is about the right time for Microsoft to be C++ happy enough to push developers to use it over just using the bare Win32 C APIs. MMC was a pretty big deal when it first came out.)
