Automatic Updates not working

I have CC and the desktop app. 

I mainly use PS, but have a few other apps downloaded. They need updates pretty regularly. 

My CC CONSTANTLY needs updates. And it notifies me in my system menu every time it needs one. I just want them to update ALL BY THEMSELVES if I am not using the program. I don't want to have to manually click update. What's the point of automatic updates if I manually have to trigger the update? It only automatically looks for updates, never have I seen them install them. 

It makes a notification on my desktop and that is really annoying because when I am doing things, including playing online games, it will minimize what I am doing to show me the new updates. And it's been doing it a lot lately. 

I do not want to disable notifications, because then I am not being notified when they are supposed to be updated (and then not).
