Re: So how'd they get it?
"What, when the computer is often turned off completely?"
Recent Intel chipsets have a feature that powers up the computer to check for updates. Probably doesn't work under Linux though...
"as to the games, odds are it'll run better under wine than doze"
Now you are just showing your ignorance. Windows 10 is simply by miles the fastest platform for gaming. Direct-X 12 is a long way ahead of other close-the-metal driver models - not to mention that people actually use it, and loads of games won't even run on Linux at all.
" it does a better job, period. "
Over what period? I use Windows because I need high end gaming and Office type applications. Linux is utterly crap in comparison for both those uses.
