Tell me how one can update a Windows system (incl. all installed applications) in a straightforward manner. Windows comes with no package manager, as far as I know.
OneGet and the Appstore might be taking steps in the right direction. Still no unified (apt-get upgrade and dist-upgrade) - but currently doing an in-place upgrade win7->win10 and I actually expect settings to be retained and programs to continue working.
For (especially) FOSS software, you might want to look at http://scoop.sh/
Yes, Windows doesn't come with a walled app repository. That's one of the benefits -- I don't have to ask Ubuntu and Debian and RedHat and god knows who else, "mother may I" before I write a program. I just do it. Though I do know people who now do get most of their apps from Microsoft's package manager these days.

You can just offer your own repository and have the package you distribute install it. I think you are confusing linux package managers with appstores.
You could have a system-wide update mechanism without a common repository. Linux distros have that: you can use as many different repositories from different vendors as you like, but there's still only one update command.
