I recently saw an invoice sent out and paid regarding an 'annual Office 365 support' charge. I would appreciate if someone could clarify how and where free upgrades to Office 2016 or 2019 are allowed. Specifically I am interested in know whether or not this non-profit organization can upgrade to Office 2016 or even Office 2019 at no charge. There seems to be 2 questions. Question 1 is the issue of activation for Office Pro Plus 2016, Question 2 is about how to upgrade Office from Office 2016 to Office 2019. Question 1, please search CMD, right-click the Command Prompt and run as administrator. Then copy and paste the command, click Enter at last. Microsoft 365, Office 2019; Office 2016, 2013; Office 2010; Redeem or activate. Redeem or activate; Office product keys. Enter your product key; Product key for Microsoft 365, 2019, 2016, 2013; Change your Office product key; Product key for Office 2010; Product key for Office 2007; Activate Office. Office 2019 is actually a frozen feature set of Office 365 prior to October 2018, so, the appearance will be just like Office 2016. If you are seeing any indication of 2019 branding, launch any of Office 2019 applications, click File Accounts Office updates check for updates.

Microsoft releases security and quality updates for the Click-To-Run (C2R) version of Office 2016 and for Office 2019, which is exclusively C2R. These updates are released approximately once a month, usually on the second Tuesday of the month.

If you'd like to verify that you're up to date, check your Office version number and manually update Office if necessary. To check your version of Office, do the following:

1. Open any Office application, such as Word or Excel.
2. Choose File > Account.

If the version number matches the most current version, you're up to date. If not, you can manually update to get the latest version of Office. To update Office, follow these steps.
