For a few years, Microsoft has realized that the best way for any user to always have their favorite applications at hand, whether they are free or paid, without having to save the serial numbers, is through an app store, a store that has already gone through several names until finally being called Microsoft Store.
The main browsers on the market, excluding Edge, Chrome and Firefox were not available in the Microsoft Store, but relatively recently, Google had included a container to be able to download Chrome from the Windows application store, a container that has been removed from the Microsoft Store for violating the guidelines.
As confirmed by a Microsoft spokesperson, Chrome was banned from the Microsoft Store because it violated store policies. Specifically when developing the application, since in the case of a browser, it must have been a developer with the EdgeHTML rendering engine, an engine that is not the one used by Google for Chromeas it uses Blink instead. On these occasions, Microsoft has slapped Microsoft back when it forced the Edge version for mobile to be developed in another rendering engine than the one used by Microsoft.
We can consider that this expulsion is merely anecdotal, and that surely, Google will not try again, since if up to now it has become the most used browser, without having to be in the Microsoft Store, I doubt that not being available in it, could harm you in something, since the company based in Mountain View, She already takes care of herself to remind us again and again every time we use her services, that we download her browser to enjoy a better browsing experience.
