I once had a user whose PC would freeze every time they tried to see their desktop. Like, you minimise something full screen and the PC would freeze for a few minutes and crawl while the desktop was in view.

Turns out they had more than 4,000 items on their desktop.

That day I learned where Windows puts icons that don't fit on the desktop (it stacks them all on the first icon's place, lol). And this wasn't even the problem they called about! They were just grumpily blaming Microsoft and working around it for years.

I guess my point is computer illiterate/belligerent people will find a way around the problems they cause and just blame something/someone else.
