The only people who "buy" Windows are those who build their own gaming machine. Even then, they usually buy a sketchy "volume license" key off ebay.
I bought windows retail, because I actually like the Windows kernel, and despise running pretty much any install of Linux that isn't just a command line to boot daemons and web servers from. I use my computer every single goddamn day, and don't ever want it to randomly break, which Linux has always done to me. The steam deck is the first Linux install that hasn't been utterly useless or shit the bed on me.
Every single problem I have had in Windows has been caused by shitty hardware, or AMDs abysmal drivers.
Enterprises pay a surprising amount of money to Microsoft usually in the form of monthly/annual pr user licenses(to the time of double digit percentages of the end user device budget) and yet no amount of badness seem to make anyone in those Enterprise departments think that they have any alternative and it's the same in the laptop space, where despite having to fork out whats often a double digit percentage of the retail price to Microsoft there is no serious appetite from hardware vendors or consumers to consider that maybe we could have a market where multiple Operating systems coexisted.
And your driver argument is exactly the weirdness here as people will absolutely hold anyone but Microsoft(especially smaller opensource competitors) responsible for bad drivers but with windows it's suddenly an valid excuse for bad experiences with windows.
