I came across a great site of screen shots of versions of Windows and other graphical user interfaces. Ah, Windows 2, I remember it well. And then there’s Microsoft Bob, which was “designed to replace the desktop of Windows 3.1 and 95 with an interface designed mainly for novice users”. At first I thought this was a joke, but no, it existed, though it turned out to be a flop. Not surprising, I say!
