Ehhh....that's "installer downloading and executing", which is a far cry from "package management". Notably, it doesn't provide dependency resolution (which is 90% of a package manager's job, IMO), and Windows' software packaging conventions don't really work well for an apt-like system, since they are intended to be mostly self-contained outside of shared frameworks.

I use chocolatey, but it's not anywhere near the level of apt-get. That's more Windows and Windows developers' fault than chocolatey's though. They've done a great job given what they have to work with.
