Hello, LzD!
More than two months without a question... it is too much! So... yes, I still have questions. :)
I would like to ask about Office Online. Can someone use it as before? When I search about it, I only find pages about Office 365.
Yes, Office Online is still available. Go to https://office.com and sign in with your Microsoft Account. It will open up with all the Office apps available: Outlook, OneDrive, Word, Excel, PowerPoint, OneNote, etc. Of course, the free versions are not as feature rich as the licensed versions are but most definitely work.
Thank you.
I saw the Install button at the right and thought that it has to do with Office 365 or my Office 2016.
