I am trying to get a list of installed programs using PackageManager.FindPackages. Some of the App reported by the following API are not
visible in Apps & Features i.e Microsoft.XboxIdentityProvider, Microsoft.StorePurchaseApp. The packages are not Framework,Resource, Disabled, System.
Any reason why they are not showing in Apps & Features?

Universal Windows Platform (UWP)
