Package managment system for Windows?

Not really, since Windows doesn't operate off a package system: applications are, effectively, in most cases, independent: shared libraries--if any exist for a given application--would be written to a system folder (%windir% or %windir%\system32, for example) by the installer for a program so that it could load the library via the fact that it exists in a directory specified in the PATH variable. (The other case being that they would be stored in the program's root install directory.)

So, not really; even open source apps don't really provide a unified method.

Jam it back in, in the dark.

I know what you were thinking of. (I was trying to explain, albeit badly, that programs in Windows are relatively independent of eachother, so managing them properly from a single tool is somewhat hard.)

Sadly, one does not exist. It would be possible to make; it would take some time, I imagine, to get working right, though.

(Also, that article needs to learn to use Gentoo before Vidalinux ;_;
Even a Gentoo LiveCD (with X) would be sufficient >_>)

There's nowhere I can't reach.
