Idk I don't think windows users are as mentally handicapped as both we and those windows users themselves like to pretend, I think they're just lazy.
Excluding like the elderly and stuff who barely know more than a pen and paper, and seemingly now children who have never used anything but an iphone, but like, average people? I'd expect they can "learn things," yes. Tbh windows isn't as "just works" as advertised either and they likely already have to learn something every now and again (though then again every fix for windows after 8 seems to boil down to "reinstall it loser" so maybe not.)
The culture of immediacy has been such a detriment on our society.
