It's been 15+ years? since I regularly used Windows so maybe I'm mis-remembering this, but I definitely remember there being quite a few WTF moments working with the Windows XP Control Panel. Lots of changes for no apparent reason, and many weird/ jarring things. Its definitely not a Windows 10 thing because I've spent roughly 15 minutes using Windows 10.
Even in Classic View, there are admittedly some items that have user interface styles that date back to Windows 3.1 (one example being part of the Fonts area), so there are some oddities. But switching to Classic View takes care of a lot of them.
For example, the German version of Windows XP renamed the entry for "Software" to "Programme und Funktionen"/"Programs and functions".
It's something that even over a decade later keeps catching me off-guard because for the longest time I was so used to look for "S like software".
And Windows 10 did it again with the whole "App" thing where I'm still somewhat confused if that's the new name for software, or if I'm installing some kind of integrated gadget from the Windows store or what the actual difference between these two is supposed to be.
I had a machine that refused to sync NTP until I went into Control Panel, even though everything looked fine in the new Settings
