Earlier this year, Microsoft announced plans to update the look and feel of the Store while continuing to make it a place to get apps, entertainment content, and games. Because the new Store will now allow developers to include Win32/64 and other new kinds of apps, Microsoft execs said they'd be adding Office, its Edge browser, and Visual Studio/Visual Studio Code to the Store. The new Store will highlight Progressive Web Apps (PWAs), as well.
Microsoft and Amazon also announced in June that Amazon would be bringing its Amazon Appstore to Windows 11. This is key to the way that Microsoft will be able to make Android apps available on Windows 11. Today's announcement about the Amazon.com storefront coming to the Microsoft Store seems to have no immediate bearing on Microsoft's plan to bring Android apps to Windows.
Officials said today that Microsoft is updating policies to allow third-party storefront apps to be discoverable in the Microsoft Store on Windows, including Amazon and Epic Games, over the next few months. And "soon," Windows Insiders will get a preview of the Amazon Appstore catalogue, including the ability to browse and search its catalogue directly in the Microsoft Store for Windows.
