It was pretty similar to modern Windows but without taskbar or Start menu.
Instead, you had a main window called “program manager” with icons in it to start other programs.
Do you have any specific questions about it?
What is that? I don’t think that’s what I had in mind. I think it’s DESQview I was trying to think of. Anyway, not important… it was just driving me nuts I could not remember.

Sorry, I think I misunderstood your question.
And I had literally never heard of any Windows 3 alternatives up to now.
To be fair, I was quite vague. I think there are multiple right answers… but I recalled one starting w/a ‘D’ and that’s what I was trying to recall.
