It's not often that anyone posts positively about their Windows 10 experience, so it is refreshing to hear! People in general will only post negative things to illustrate problems they are having.
'Tis the nature of "help forums" of virtually any type. I participate on several automobile related forums as well, and "trouble talk" predominates.
I have, for years, tried to get people to understand that venues people turn to when they have problems are not, in any way, able to be used as a metric regarding either the incidence or prevalence of those problems. The sample is grossly skewed, and that's OK because we're here to help in solving those problems. My analogy on the car forums is, "If you believed what you read here were characteristic of automobiles in general they would not be wildly popular around the world."
But, as you say, the vast majority of users are happily humming along with Windows 10. The 5 machines in my household have had almost no "burps" with Windows 10 since 3 of them were upgraded to it and the other 2 purchased with it as the OEM OS. It took me a while to warm up to it, and particularly the flat-look UI (which I still do not prefer to the old Aero UI), but I now like Windows 10 better than any of the versions of Windows leading up to it (and I've been in "this biz" since Windows 3.1).

. . . the presumption of innocence, while essential in the legal realm, does not mean the elimination of common sense outside it. The willing suspension of disbelief has its limits, or should.
