If what you tried doesn't work, Windows 10 allows you to go back to a previous version that worked. I know that you can postpone the update for a limited time (6 months - 1 year or so). Go to Start > Settings > Update and Recovery. Press the Get Back and Windows 10 will downgrade to the previous version where everything worked.
However, the Creators Update is available which is past Anniversary Update. Try installing it and then test the Media Jukebox and the other apps.
Also, before going back, download the latest build from the official forum.
