Left off Windows 11. The new one is the most logical one yet. Don't like that much about Windows 11, but the control panel is improved.
What frustrates me about Windows 10 is that each one has settings which are exclusive to it, so you always need both, and never know where to look.
More importantly, they've gotten pretty good about linking into legacy Control Panel applets from the modern settings app-- so, even if a setting hasn't been migrated yet, you should be able to find a link to it in a logical place from the new Settings app. That's not new in Windows 11 (Windows 10 is pretty good about it too, for the most part), but the Settings reorganization in Windows 11 helped this along a bit.
