*.cpl, *.msc, etc are Windows sysadmins' (and developers') bread and butter; Microsoft will never get rid of them. I am betting (maybe hoping...?) that Windows 12 will undo the changes in Windows 8, 10, and 11 as bad experiments and return to what Windows has done best, which is discoverable GUI configuration. Let's see.

You're much more "glass half full" than me, but one can dream.
