Microsoft AutoUpdate is an application that periodically checks, downloads and installs Microsoft Office and Edge updates. Occasionally this tool is updated by Microsoft and is deployed to your computer using Managed Software Center. As noted in another solution article if the application in question is being updated and it's running in the back or foreground it will not proceed until it's closed.


If you notice Microsoft AutoUpdate is unable to install because it is open please check the following:

  • No Office applications or Edge browser windows are open. Even if the window is closed the application may still be running. Please check for a white or black dot under the icon on the Dock to ensure it is not running. See below for an example of Microsoft Autoupdate running in the foregroundExample of a running application
  • If you see no applications running in the Dock open Activity Monitor from your launchpad and do a search for Microsoft or MS as shown below. Highlight Microsoft AutoUpdate if found and click the X in the upper left-hand corner and choose Force Quit.

Managed Software Center will start the install automatically once the process(application) has been quit.
