That’s what I’m saying. Windows installation is idiot-proof. And I’m sure there’s enough people who maintain their own systems or at the very least have had to install Windows for one reason or another that to say that “almost no one” who runs Windows installed it themselves is just the “Linux Master Race” talking.
PC building is niche, yes, but do you think “almost no one” builds PCs, like OP said? And that’s not even including the people who’ve had to install Windows on a pre-built system for one reason or another.
My point is that OP sounds like a smug Linux user shitting on people who use Windows. Even 5% of Windows users is too big a group of people to be described as “almost no one” simply because of how big the userbase is. That would be like saying, “Almost no one installs Linux” because Linux only makes up a small portion of the worldwide PC userbase.
