Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello !
On your laptop, open any Office app. You should see a window opening, stating "You've got Office !", as seen here
If you do not have any prompt when opening an Office app, open the Microsoft Store on your laptop > click on "Library" in the bottom-left corner of the window > click on "Included with your device".
You should find Microsoft 365 here.
Please let me know if you have any other question !
