Package managment system for Windows?

Is there, by any chance some 3rd party software package/repository solution (think APT or Portage) for Windows? It's such an ordeal to download all that crap seperately and keep it updated. A one-two click solution would be neat, at least for freeware/open source software.

Jam it back in, in the dark.

I wasn't thinking of shared (or rather unshared) libs, rather the ability to open an interface, select the program to be installed, hit 'ok' and have it set up a minute later. And with all the binaries available at Sourceforge and other sites, such a system wouldn't even need its own servers, just download sources and silent install "recipes" so to speak (much like Portage on Gentoo does).

While I was googling around for such a program, I found this article which pretty much sums up how I feel about using Microsoft OS's these days (or set one up in this most tedious fashion).

There's nowhere I can't reach.
