Hit a wrong key and ended up with all these faces displayed instead of the image I wanted to edit. A Google search for eliminating people view didn't help either. I finally found the tiny cartoon people icon towards the lower left of my screen and toggled it off, and all the detected faces disapperared. (I'm sure some of them will haunt my dreams tonight.)
Somebody must use this feature or Adobe wouldn't include it, but it's totally annoying and useless to me. Adobe needs to step up and provide a way to delete / stop / eliminate it from Preferences on Windows machines. I came very close to heaving my computer out a window on this one.
