Thanks, I think I may try again some other time, when I’d explore theming. I have never tried (and needed) my system to look like Windows, as even when I used Windows itself, I was making it a mix of the best things from macOS and Linux. Here, I surely made a mistake of not hiding the attempt and showing them the modern Gnome, which is pretty simple for a newcomer. A non-techie friend installed Fedora Workstation (to be precise, Silverblue) once, and in general was very positive about his impressions.

Also, an interesting thing about tech support: I’m much more qualified with Linux than they are with Windows. And I’m able to help them adapt, by investing inadequate time (like an hour or two a day, if needed), asking nothing in return. Yet, people are not willing to try, perhaps they are afraid, or have some stereotypes of Linux maybe.
