Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
This issue has been bothering me too for months. I made a setting change today and so far the Restart message has not come back.
Windows Settings
> Privacy
> Diagnostics and Feedback
--> Diagnostic Data: BASIC
**This is what I changed below**
--> View Diagnostic Data: TURN ON
it took me to App Store to download the software.
This worked for me as well! :)
I'm going to try turning the "View Diagnostic Data" back OFF and see what happens.
