In windows 10 you can enable "show hidden files" but also enable "hide protected operating system files" which keeps copies of desktop.ini from appearing on the desktop.
That's not just in Windows 10. There have been separate settings to hide/display the two types as far back as Win95, as far as I recall, and even before there was a GUI environment that "displayed" files in directory/"folder" "windows", the attributes determined whether those files were listed by default along with ordinary "user" files...
hiding extensions. I can't believe that's still the default setting.
I had completely forgotten that hiding extensions even
was the default. That
is awful. Aside from the security issue (assuming a given user even knows what to beware of as far as that's concerned), just from a functional standpoint, it would drive me nuts not knowing what file type any given file was at a glance.
But then, I also forget how many "average users" are only vaguely, if at all, aware of Windows directory structures (excuse me, "
folders"

), and just dump their files in the default like Documents, Music, rather than organizing them in any sensible way, being reminded mostly when I try to help a family member deal with something and I ask them "where do you put
XYZ files?", only to be met with blank stares (as if to say "what do you mean, 'put them'? I don't
put them anywhere, I just click on 'save' "...)
