Microsoft tried, they have the Windows Store and certain programs push you to use it, but UWP is an absolute disaster both from a user and a developer perspective so nobody wants that.
Microsoft took a good idea (software repositories) and turned it into a bad idea (software repository controlled by microsoft and you're not allowed to add/install/validate other repositories).
They could have built (hell, even USED) apt, but they built Store.
