"Hide extensions for known file types"
That option set to default has by definition ensured that the clueless remain clueless.
It has been more than two decades now that Microsoft foisted itself on the world in a particular set of events. During that time, had the masses grown accustomed to at least seeing entension names, perhaps today a much larger portion of the population would at least have half a clue of what is being said when they heard "do not click on executables".
Instead, thanks to that option, most people probably don't even know what an executable is, much less how to recognize one.
I'm sure spammers all over the globe are blessing Microsoft every day for that blunder.
