Microsoft released the November 2019 non-security Microsoft Office updates that fix issues and add improvements to Windows Installer editions of Office 2016. None of the Office updates released today apply to the Click-to-Run Office apps, like Microsoft Office 365 Home. The updates can be downloaded from the Download Center or from the Microsoft Update service for manual installation. Some updates may require a restart for the issue to be completely addressed on your Windows device, as is the case of the KB4484137 update that requires KB4475552 to be installed.
