Once I built a PC for gaming, and then nostalgically remembered all the old versions of Windows - from 95 to 10. I wanted to see how it all started and what had changed over the years. And I found an extremely useful infographic
https://www.dailywaffle.co.uk/2021/03/the-evolution-of-windows-os-infographic/ where you can clearly see what features were added, why the interface changed, and how all this made it more comfortable to use. Really interesting and informative.
