Windows 10: Office files suddenly disappeared, possible conflict with office 2016 and 365?

HI, A laptop WIN 10, Office 2016, single SSD I'm working had a primary folder on the desktop with numerous folders under it with files inside there, suddenly a few folders and their contents disappeared. In addition, a larger majority of the office files in virtually all other office files have disappeared, yet those folders all remained intact. There are no backups, I looked for previous versions/recovery points, I set hidden files to visible, I've run a clean boot, virus scans multiple types, ran 2 different programs checking for deleted files, Scan disk came back clean, verified fi

Office 365 or Office 2016

I am having a similar problem. I have never to my knowledge indicated that I want Office 365 or an Office 365 "free trial"; I have Office 2016 installed on my laptop. The application list on the start menu does not include Office 365. However, Settings/Apps does indicate that it's installed. Today my system was co-opted by Office 365 Click-to-Run grabbing both disk and CPU; this has not happened before.

I bought this laptop two years ago, bought Office 2016 and installed it via Microsoft download as no installation media were provided. I uninstalled the annoying "Get Office" application at that time and have been a happy Word user until earlier today.

I don't know if this is relevant, but this behavior started right after Windows Update installed the August 14 cumulative update (KB4343909). No updates to either Office version appeared in update history.

My questions about how to deal with this situation are:
--Would the Uninstall option in Apps get rid of Office 365 entirely and leave Office 2016 in place and working?
--Is there an effective way to disable or stop Click to Run and keep it stopped?
--Should I change the update setting in Office to Do Not Update? I did try to look at the Office update history, but all I got was an Office 365 sign-in screen--useless because I don't have an Office 365 account.

Any suggestions would be greatly appreciated. Thanks very much in advance.

I'm thinking option one is going to be my only option. I'm fine with that as long as I can get Outlook to work with my ISP's pop3 e-mail. Last time I tried that with the new 2016 install I could not get it to work, no way no how. All the same settings that work with the ISO install?

EDIT: I should mention, for me as far as I know, neither of these options are a subscription. They use two different keys but they are perpetual one time activation licenses. I only ran the new download briefly though, as I could not get outlook to work. I bailed and went back to what works.
