Some people still want to feel like Windows is something they own, like back when it was something you installed on-top-of DOS. Taming the hostile mess its become is still rarely worse than de-bloating a new OEM PC ever was, and if you use your PC rarely-enough, there's hassle aspects that blur into near-parity versus Linux(updates, anyone?)
... share a PC with others, and just keeping Open-Shell(plus PowerToys and/or StartAllBack, or sometimes Rainmeter for a laugh) on one's profile looks sufficient, versus dual-booting or whatever. Personally, my Laptop can go un-used(by me, anyways) for months and months, and letting my family use it helps keep it up-dated and let's me know if problems arrise before I run face-first into them in a moment when I just need the thing to work.
I'm looking-forward to each of my kids having their own capable laptops(just ONE more ...), but until then, Windows updates are stupid-prone to breaking dual-boot, only one of my kids likes/uses Linux half-so-much as I do, and even he is in more of the tweak-it-until-it-breaks-and-start-over dabbler stage, so I let him keep to his own laptop and a pile of old used ones(and consoles...) that are older than he is. 99% of what I would use it for in the mean-time, I just use my phone.
I almost mentioned "work-flow" en lieu of the list of options I went with earlier, but basically, over time you build-up habits and certain ways of doing things that to you are "that's just how I do things, why do you ask?", hard-or-even-near-impossible-to-explain, and look like a lot of work to another person, but add like, (often less than)a minute to your day.
I was trying to down-play the hassle without diminishing it, but its like learning a new tool or app or form at your job. Maybe noticably-annoying-or-even-painful at first, but once you establish your own "why?", which you'll probably forget or remember in-place of the "why?" they told you, you work it out, work it into what you were already doing, and it becomes something like background noise.
Now, an AI would write you a book on how-what-and-why-it does x, which may or may not in any way resemble what it actually does ... I am not sure on my worst day I would actually recommend directly asking about that, versus, "are you an AI?"
