Yes and No depending how you look at it
personally i have not touched windows since the xp days
Phones, tablets, servers, routers and on and on.
The US Navy uses it, the FAA, the French parliament, universities around the world etc.
It might be an unfashionable view, but there's no way I could tolerate it as an OS for a laptop or desktop. It is the backbone of a huge amount of our lives these days though.
