Are there OSes for a single user?

Question

Operating Systems

I live alone, I'm the only one who uses the computer. Tell me, please, are there operating systems for computers designed for one single user? In which there are no administrators, no users, no rights, accesses, permissions and other absolutely unnecessary and meaningless crap.

Answer 1

Admin is not an access right, but the role of a person working at a computer.
The operating system is not a program with one task - but a complex for solving different problems, incl. run different programs in different conditions.
The only way to get what you describe is to ask to be done, configured and hidden from you all unnecessary, turning a universal operating system into a specific solution.
For these purposes, there are corresponding versions of operating systems, often not popular (because they are used by integrators), the same windows embended or how ltsb versions are praised here ... but all the same, access rights are not removed from there, since as soon as you go out into the world the Internet, as your computer is no longer only yours, but also at least the owner of the server that your browser has accessed, and you need to somehow distinguish between who can and cannot do what ...
