This is kinda how I feel about Windows these days. It’s interface, directory structure, shudder the registry, user specific apps (from MS Store or Winget), buttons being inserted into the menu bars on some apps, but not others, button sizes being different sizes, some parts still using the Metro interface. The whole thing either needs a re-write, or should be dropped and something new to replace it. Don’t even get me started on things like the eventvwr hanging for 20 seconds after it opens, event tracer API, their in-house abandonment of powershell modules once powershell was open sourced, Windows containers being a disaster, etc.
raises pendantic finger Ah-hem, sorry, but KDE Plasma isn’t an OS. It’s a desktop environment. For an OS bundled/built-around Plasma then Kubuntu or KDE Neon are both Linux distributions that would better fit that description.
