You're a miracle worker. :)
Failure to read what's on the screen is one of the biggest reasons why "non computer" people don't get things done with computers.
In any case, the longer label could have been implemented as a simple mouse-hover tooltip, instead of an extra button alongside the primary button that expands to a menu with a single item (with its own icon too!)
I'm not just comparing it to macOS; the Windows UI is heavily flawed not only in terms of efficiency in usage of system resources, it is inconsistent with itself, and baffling no matter which school of design you adhere to.
The option button was just one of the immediate examples I could point out in a quick reply. There is still a lot to pick at in that screenshot without comparing it to any other OS.

As an aside, I don't think that "average" or new users are a good gauge of how well-designed a system is; people can learn and put up with horribly unintuitive interfaces out of necessity when they don't have any better alternatives. Just look at computers and phones and other devices and systems of only 20 years ago. Many will make you go "how the hell did we live through that?!"
I see the MacOS Finder and see unlabelled icons. My elderly folks are terrible at remembering what various icons do, and what error messages are for, etc. I've trained them to pause and read the words on the toolbar, read the words on the window, etc. as they're generally self-explanatory.
So the finder that is more convoluted for a more proficient user, is the one that my folks can actually more reasonably navigate.
Okay, your criticism is on point: the Explorer Options button has a redundant click. To me, that would matter if I ever used anything other than keyboard navigation. To my mother, father, and sister, "yay! It's f'n labeled!"
My nieces don't give a damn either way, because they're too young to care about one unnecessary click, and they don't forget what the icons mean.
Your point isn't wrong, it's just not that clear-cut an issue when dealing with different people with different levels of proficiency and needs.
But the fact that we're down to "labels vs. reasonably intuitive icons, plus or minus a redundant click" suggests we're well into the weeds of trivialities.
