What happens when I upgrade a Windows 8.1 Universal App to a Windows 10 Universal App? RRS feed

  • Question

  • Let's say Alice has a Win 8.1 universal app in the store, and she replaces it with a new appx package containing an updated Windows 10 Universal App.

    Bob has Windows 10 and Windows Phone 10, he comes along and installs it. Yay, it works on both of his devices.

    Carol only has Windows 8.1 and WP8.1.
    • What happens when she tries to install it?
    • Does it install?
    • Does it fallback to the old 8.1 package?
    • Can she even see it in the store?
    Can someone please answer these questions for me?

  • Users will get the most appropriate (highest versions) package that applies to the device they are installing on. See
