Set up Microsoft AutoUpdate
Open any Office application such as Word, Excel, PowerPoint, or Outlook.
On the top menu, go to Help > Check for Updates.
Important: If you don't see Check for Updates on the Help menu, download the latest version of the Microsoft AutoUpdate tool from https://support.microsoft.com/en-us/kb/3133674. Run the tool and then start over at step 1. The Check for Updates option now appears on the Help menu.
Under "How would you like updates to be installed?", select Automatically Download and Install.
Note: If you want to manually check for updates choose Manually. If you want to be notified of new updates but not apply them automatically, use the Automatically Check setting.
