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.
