>>106140884 (OP)A long time ago there was an operating system called Unix. Everyone used it for everything because it just worked. So when people were designing new operating systems they did it the Unix way, because if it ain't broke don't fix it. This produced a family of operating systems called "Unix-like", which power every smartphone, Mac and Chromebook. They are also the industry standard for web servers, because servers need to just work all the time.
Out of this family, Ubuntu and MacOS have the most user-friendly interfaces for desktop use. MacOS, however, is designed to run on a specific set of very expensive hardware, whereas Ubuntu is designed to run on anything with a processor. So when you boot it for the first time you will be amazed by how fast everything runs and never want to go back.

So they reinvented the wheel with lots of new features that sometimes work if you have the latest hardware. They configured everything from a single registry (horribly insecure) and handled metadata with alternative data streams (literally begging for viruses).
Windows became popular with offices, because it comes preloaded with a complex toolkit for administering a company network and managing permissions from one place, so you will never again have to do pesky chores like calling a person and asking them to press a button. Having cornered the office market they quickly cornered the PC market in general, as office monkeys wanted the same system at home that they had already learned to use at work.
The children of the office monkeys wanted to play with the PC, so Windows then cornered the games market until the best games were written exclusively for Windows. Fortunately, Valve corporation have now liberated us from this with the Proton compatibility layer, which allows you to play games designed for Windows without ever running Windows.
