There are two versions of OneNote on your PC – OneNote 2016 and the Windows 10 OneNote App. As you may know, Microsoft are no longer developing the 2016 App and there is no OneNote 2019. I recommend you have a look at using the Windows 10 App – it does not have ALL of the features yet but they are on the way and it has many great features the old 2016 version does not have.
To set the new app as the default app
- Go to settings
- Choose Default app
- Go to “Set defaults by app” at the bottom
- Change the OneNote entries to the OneNote app
