Solution to fix KB5094126 breaking OneDrive integration w/File Explorer

With Windows update KB5094126 multiple users are reporting OneDrive integration failures where the application becomes inaccessible through Windows Explorer after installation, though web-based access remains functional. Searching the Internet one can find several suggestions such as reinstalling OneDrive, running ‘OneDrive.exe /reset’, or various registry edits; none of which seems to fix the behavior.

Welcome to the forum. FYI Hiding a monthly cumulative after uninstalling it won't stop the code within the cumulative that broke your onedrive from coming back. It will be part of the next month's cumulative (unless MS acknowledges there is a problem and fixes it before then). IMO pausing updates would be a better solution until there is a fix.

I thought wushowhide.diagcab tool had been deprecated.

It is deprecated. That's why it's not longer listed for download, and you have to "know" the legacy URL.
But it still works.

I agree, rolling back and stopping updates is a stopgap measure. MS will either fix the issue in a future update, or release a newer OneDrive client. The latter is probably easier for MS since they don't have to wait for the next scheduled update.

Thanks for the tips. Pausing the updates can only be done for 5 week intervals, is that correct? Hopefully, this will be fixed by that time?

Nah, you can pause updates for a long time. Your man Shawn has you covered.

It's still useful if you wanna skip updates for example.

In my case I prefer to install BIOS updates manually and from the manufacturer, instead of letting Microsoft push their own update. I had a really bad experience letting them handle that for me... I always hide firmware updates unless I'm ready to install those (like with CA 2023 case...)
