Stop Office BACKUP THIS DOCUMENT prompt

Sorry to report, this doesn't correct the problem.

I added that key & value to the registry, and even rebooted.

The nag is still everpresent.

BTW, why the "" around the key? Just to be thorough, I've tried it both with and without the quote marks, with the same disappointing results.

The quotes are just how regedit export represents string values (the key name). I will add a snapshot of how it looks in regedit.

I have not had the nag appear since I added this (4 days now). I am running Win11 Pro, 22H2, and Office 365. OneDrive version shows as "Build 23.226.1031.0003".

Thanks for clearing that up question about quote marks.

I'm still getting the nag, whether on newly-created Word documents or existing ones that I open to read (not revise).

Windows 10 Pro 22H2 Build 19045.3693

OneDrive Build 23.209.1008.0002 (64-bit)

Sorry it didn't help. It is still working for me; opened several Excel and a couple Word docs this morning -- still no nag for 5 days now.

Perhaps the "KFMBlockOptin" was implemented in a later version of OneDrive? Mine is a higher build number (I assume because I am on Windows11 and you are on Windows10).

Hopefully some more folks will try it out, and that might establish a pattern.

ARRRGGGHHHH.... 5 days without the nag banner, but it returned this evening. Opened an Excel file and got the stupid "BACKUP THIS DOCUMENT" banner again. So that policy setting did NOT fix this.

It seems like every company is trying to push "subscription" services, as they want sustained monthly profits. My cable company wants me to buy cloud DVR storage, Apple wants me to buy more iCloud storage, and Microsoft wants me to pay monthly for increased OneDrive storage. And all of them will do everything they can to make it the "path of least resistance" with repeated nag screens. <sigh> I get closer every day to just ditching Windows and using Linux (not perfect either, but tired of being nagged and coerced into services I don't want).

Thank you very much Scott-uu for you accurate and informative, albeit disappointing response! Especially the clarification that Microsoft, a software giant, corrupts the definitions for the most basic of computer actions, like "backup."

And thank you Mark8352 for sticking with the question and ignoring any non-answers.

I am furious with Microsoft in PUSHING their Onedrive nonesense. My wife somehow accidentally had her entire store of files tumbled up in a Onedrive invasion. It was a mess restoring her local drive because I found it to be glitchy with that mirror of backwards files. Broken mirror in my view.

I am sorry that I have no solutions, having hunted through settings and punched different options on both Win 10 and 11. I expect that it will take a software update. But will Microsoft management listen to feedback? (he asked rhetorically)

It is this sort of thing that is causing my entire family to move to Apple products, my wife and I are the only ones left.
