Your Office license has expired and need to replace it with a new product key? Need to change Office product key because it’s already activated by the maximum number of times? In this tutorial we’ll show you 2 easy ways to change Office 2019 / 2016 product key without re-installing.

Method 1: Change Office 2019 / 2016 Product Key from Office Application
