I would say around 15 years ago, it was Windows XP

But it did MOST of the times...

Oh, I don't know how it is nowadays, I have switched to Linux since many years ago...

Very often sfc /scannow will ask for an installation media, which, in a corporate environment, means sending the machine to onsite support for either "fixing" or "reimaging". It's basically the command you should try first if you don't want to help someone fixing the issue. "See? There is something wrong with your installation, you should fix that before doing anything else..."

I used that trick a few times myself to get rid of poorly behaving people.
