My understanding is that will never happen, because some (most?) people want to CHOOSE when and which updates to download
But, since I don't work for Adobe, that may be a false understanding
Have you asked the people in that forum? http://forums.adobe.com/community/photoshop
Kevin, every time you log out of the CC desktop App & log back in, the updates start.
However there is no option for autoupdate as John has correctly mentioned.
