After mulling over it for close to 14 years, it seems Microsoft is finally ready to kill off the Windows Control Panel soon. An official confirmation has been posted on its website.
Control panel largely accrued content - it is generally navigated via left and right click which works great and is stable. Things don't vanish.
Settings, on the other hand, is left click only navigation mostly. It also changed constantly (usually for the worst) - tutorials written 2 years ago are no longer valid because access to that setting was removed. This makes using settings to fix things a real nightmare.
But luckily each item has a lot of "maybe you were looking for X or Y" at the bottom since you can't find anything in there. So just click anywhere, and scroll to the bottom and you'll find what you want in 2 or 3 screens.
Unless it's been removed. Then you just ask the resident IA.
