I don't see how this question is not constructive. It is simply asking for a package manager for Windows with some certain properties. Being non-constructive would mean (as I would understand it) that no constructive answer can be given. I fail to see how that is. Even if the answer is "no, there is no such thing", it would be constructive.
I also don't see why this is a bad question (as said in the discussion here). It asks for some software with some properties. I have asked it on StackOverflow because those properties make it esp developer related.
Any answer to this question would be helpful to all other people with the same question.
Can somebody elaborate why this question or any answers is of negative value to SO?
