Windows

In November last year I wrote about the forgotten and obscure feature of early Windows 95 builds that lets you run Windows 3.1 in a window on Windows 95. Since then I was wondering if this would still work on the final build (950) of Windows 95, considering so much has changed since build 58s.

I won't spoil it.

Reminds me of OS/2 2.0

OS/2 2.0 (1992) had a full screen Windows 3.0 environment, which also had a minimized icon that would switch back to OS/2 when clicked. In order to make this work, Windows needed to defer memory management to OS/2 via DPMI. It also had a "seamless" mode which used video driver trickery to display Windows on the same desktop (and overlapping with) OS/2 applications, and of course that needed the dual mouse drivers etc.

Seeing this makes me wonder how much code, or at least inspiration, was shared between the two.
