The first file seems to contain the auto-update setting for Creative Cloud, while the second seems to contain auto-update settings for the programs Creative Cloud manages, identified by their SAP codes.
Would reading these config files be a reliable way of checking if Auto-update is enabled?
Does the com.adobe.accc.apps.71C332906067B5240A495FB3.prefs file's name change? That big string of jibberish at the end seems like something that might get changed every now and then.
By default, the auto-updates of the creative cloud desktop app and CC apps are enabled (which is optional) and you can manage a few settings or set some restrictions while creating a managed package from the admin console.
