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.
I thought your question was clear for what it’s worth. If it was Windows 3.0 era you’re probably looking for ViewMAX (from the same company as DR-DOS, which was an MS-DOS compatible operating system, maybe that’s where the ‘D’ comes from?). I vaguely remember reading (or maybe watching) a good feature about it online a while ago but I can’t find it unfortunately.

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.

Digital Research DOS, of my memory is right
