Take a look at the migration process for single Windows Store or Windows Phone 8.1 apps and for Windows 8.1 universal apps. Apps built for Windows 8.1 run fine on Windows 10 devices, but to take advantage of the many new features in the Windows 10 platform or to extend your app to run on additional device families, you'll need to migrate them.

    So how do Universal Apps help with lack of Back Buttons on Windows Tablets (And desktop) I have heard talk of a "Global Back Button".

    Does this mean Windows 10 Tablets will finally come with proper Back Buttons (and Search/Cortland) like We have on Android Tablets ?

    If I have a windows 8.0 silverlight app and i do a re implementation to a UAP app, How do i handle upgrade of the app through the store ? if a current user upgrades their phone to Windows 10 is there a way of upgrading the application or is it now a separate app essentially and they would have to uninstall the existing app and download the new UAP app ?

    Thanks for sharing the alternate link,
    Could you please guide about its configuration or how could I update my windows 8.1 project to universal app for windows 10 by using this script?

    Attempting to move 8.1 Universal to Windows 10. After running this script VS reports that "This version of Visual Studio is unable to open the project. The project types may not be installed or this version of Visual Studio may not support them." Windows 10 build 10240, VS 2015 14.0.23107.0

    Any idea what direction I can try? Thanks!
