I think just saying "installing the OS" is a bit of a trap, that's step one, and important step but then you get to all the different subsets of features and software that they use, including not included in the OS or its repos.
When you're looking at consumer usage of a PC for anything that remotely makes sense to do on that platform I think windows has the advantage of decades of a different software ecosystem. Cumulatively there's a huge broad library of software that linux can't touch, or gets partway there but falls short. For example I can tag music files on linux, but it's painful compared to something like Mp3tag (which has been going for about 17 years). Or if I want fan control on my 9 year old intel platform I need to learn about and add a kernel parameter and manually detect sensors before I get started whereas it's straightforward on software available on windows.
