So how to find the AppName of an UWP that isn't returned by Get-AppxPackage? However this directory is owned by TrustedInstaller and even as the computer administrator you don't have the necessary permissions to view the contents of the directory. UWP apps are installed in C:\Program Files\WindowsApps. The PackageFullName is also the name of the executable. A is the AppName, B is the Version, C is the Architecture and D is the PublisherId. This can be broken down into four sections separated by underscores: 'AA_BB_CC_DD'.
The PackageFullName will include the AppName plus additional information: Microsoft.WindowsCamera_2015.1211.10.0_圆4_8wekyb3d8bbwe Using Get-AppxPackage, UWP apps will return AppName as 'Microsoft.WindowsCamera' for example. Moreover Get-AppxPackage didn't return my app at all. AppName is not the same as the application name. The app I'm using was created in Microsoft's online AppStudio as a Windows 8.1 app. However Assigned Access will once again launch the app.
Interestingly, opening the control panel dialog for Assigned Access will show the user as configured, but the app still isn't listed.
Issuing 'Set-AssignedAccess -AppName -UserName ' from an elevated PowerShell configured my app for Assigned Access once again.
