This is incorrect. I had the same issue supporting my family members on good hardware with windows. It was just too common that software updates broke things, random adware would get installed when they clicked on things, etc. This was windows vista/7 era and when I made them switch to macOS the problems just went away. I think apple seems to be better about making it so non power users can’t accidentally mess things up so much.
It doesn’t help that the windows install for a printer includes some huge print center bloatware if you accept defaults and for Mac it didn’t prompt for anything like that (same printer plugged in with usb).
I can’t even imagine trying to support them on the new windows with the advertisements and changing stuff in the start menu…
