Am I using Office 2016 / Office 2019? How can I find out which version of Office I have?

To see whether you’re running Office 2016 or Office 2019, run MS Word and look for the date in the loading screen. Alternatively, open Word. Then click "File", then "Account". Then you’ll be able to find the version number there.

If you purchased Office 365 (the Office subscription package from Microsoft) then you already have Office 2019.
