Desktop OSes are a (very visible) minority, and it's the opposite way in my opinion: a desktop OS is an OS + a large suite of tools + a shell. It's literally something that operates the system so that every program written doesn't have to handle all the low level IO, that enables task management, etc. https://en.wikipedia.org/wiki/History_of_operating_systems https://en.wikipedia.org/wiki/History_of_operating_systems
