I'm not interested in defending Microsoft. However, things just stop working in Linux & OSX too, so it's not fair to insinuate that this sort of behavior is Microsoft-specific. I used to run Ubuntu (arguably one of the more user-friendly distros) on my iMac using rEFIt (before rEFInd was around) & that'd take a **** after every major update, resulting in me having to go in & manually configure refit.conf in order to boot. If I were a more casual user, that'd be a deal-breaker (nevermind the fact that they'd never figure out how to install rEFIt or Linux). If that had been my only computer, I'd have to go to an Internet cafe & scrounge the web for solutions that'd permit me just to get back into my OS. I've also had issues with Ubuntu locating available wireless networks (this'd usually be resolved by a reboot). Granted, it's difficult to blame the kernel for everything bad that happens, which is a convenience that Linux users have over Windows users in many cases. I guess that I'm just saying that everyone's **** stinks. I remain unconvinced that any Linux distro is more user-friendly than Windows 10, & that goes from nearly everything, if not everything, from installation to everything in the user space, really. There's other factors that make this more likely as well, such as the probability that these people have used previous versions of Windows. If Windows 10 doesn't boot, that's a quick fix for any Geek Squad n00b or maybe even a slightly geeky family member or friend. I don't think that those same folks are going to repair your Linux installation. I've worked for one of the larger computer repair companies & one of the larger communication companies, & I can tell you that the former didn't deal at all with Linux & the latter would only help you out if you knew how to do things like find your IP address, release/new, ping, etc. & they sure as **** weren't going to help you find Terminal (they'd literally tell you that their policy was to no give any Linux-specific instructions) like they would for OSX or Windows 10. I think that if you think that Linux is as simple to use as Windows 10 for a casual user, you're probably so many tiers beyond said designation, that you can't even remember what it was like.
