Thank You! And wow, talk about obscure. Using the below I was able to find the following post with all four GUIDs/URLs: https://social.technet.microsoft.com/Forums/office/en-US/4cdc901a-ae64-46c5-a1df-f0193db04768/monthly-updates-for-office-365-2016-using-clicktorun?forum=Office2016setupdeploy

I believe that this registry value is changed to point to a different URL for whichever channel you choose: HKLM\SOFTWARE\Microsoft\Office\ClickToRun\Configuration\CDNBaseUrl In my case, on a machine running First Release for Current Channel, the value is set to: http://officecdn.microsoft.com/pr/64256afe-f5d9-4f86-8936-8840a6a4f5be Another machine, running Deferred Channel, is set to: http://officecdn.microsoft.com/pr/7ffbc6bf-bc32-4f92-8982-f9dd17fd3114 Unfortunately, I'm not sure if that registry value will be there if Office 365 is set to use a network share for it's update path. In that case a different value is used: HKLM\Software\Microsoft\Office\15.0\ClickToRun\Configuration\updateurl From what I'm reading, I wouldn't expect to find updateurl and CDNBaseURL both on the same system.
