I could swear that I've seen a few articles detailing reg keys that can be changed to switch the update branch of an existing install, but I'm not finding them now.
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.
