Microsoft really wants Local accounts gone after it erases its guide on how to create them

This is a most excellent place for technology news and articles.
Ubuntu is basically what you are describing.
I would say it is openSUSE Aeon.
An immutable distro that you install and it "just works". Applications come in via the onboard Software Manager (using Flatpack). It is almost impossible to break, as the system itself is read-only. If an update should break something, the OS rolls back itself. It can do this, because it's basically updating what you'll get after the next reboot, not the running system. If something goes wrong, it reboots to the working version.
Still in development, but super stable.
Edit: spelling
I tried it back in 2012. I hated it. Little icons on the side of the screen. No taskbar. Blech.
You tried it 12 years ago. So before Windows 8 came out? Think of how much Windows has changed in that time. Linux distros have changed as well, but they have focused on usability with each change.
They have a taskbar and stuff now I think
