Microsoft simplifies privacy settings in Windows 10 Fall Creators Update and gives more control over app-level permissions.
Within the setup process users will have easy access to privacy information and how to use the data. In Windows 10 Fall Creators Update users will be prompted to provide permission before an app can access key device capabilities or information such as your contacts, camera, microphone, calendar and etc.
This rule applies only to applications that were installed after upgrading to Windows 10 Fall Creators Update. In order to review and manage your existing app permissions, head on to Start → Settings → Privacy.
