File History problems after installing KB5124008, KB5126052,KB5126146, KB5122878, and KB890830
This morning, I ran Windows Update on two Windows 10/11 computers, but the file history feature stopped working completely after the update.
Previously, after updating KB5121003 and KB5101684, files could still be backed up to the D: drive normally. The "Last Backup" time in "File History" is not updating correctly. Newly created or saved Word documents, pictures, videos, etc., still show "No previous version available" in "Content → Previous Versions". No folders were corrected; their dates are automatically updated.
After running Windows Update again today, the file history feature stopped working on both computers. The File History panel pops up but cannot be used, prompting for a hard drive connection. (The hard drive is connected and I've confirmed it can read and write.) resulting in an "InconsistentState" entry in C:\Users\User\AppData\Local\Microsoft\Windows\FileHistory\Configuration.
I'm very angry. If Microsoft doesn't address this, I'll keep complaining. If anyone else has encountered the same situation, please leave a comment below. You can also check Microsoft Q&A or the Microsoft Community Hub.
The five updates installed are:
September 8, 2026—KB5122878 (OS Builds 19045.7725 and 19044.7725)
September 8, 2026-KB5126146 Cumulative Update for .NET Framework 3.5, 4.8 and 4.8.1 for Windows 10 Version 22H2
2026-09 Security Update (KB5124008) (26200.9445)
2026-09 .NET Framework Security Update (KB5126052)
Windows Malicious Software Removal Tool x64 - v5.145 (KB890830)
Deleting the %LocalAppData%\Microsoft\Windows\FileHistory folder also failed.
Furthermore, "File History" itself is not listed in Microsoft's "Deprecated Features List." While other backup features suggest that Microsoft has no plans to discontinue it.
Microsoft is going to pretend it doesn't exist.
These worked normally before the update but stopped working afterward.
This is to inform other users experiencing the same problem.

The problem only seems to get worse. I have a laptop and an all in one computer and it is not working on either one no matter what I try. I wonder if they just want to force us to purchase a back up plan.

I have the same issue since Tuesday's update. The updates installed that day are (KB5124008) (26200.9445)
and (KB5126052).
We should report this to Windows Latest and get Microsoft to acknowledge that this update caused the file history issue to be disabled.
On W10, after KB5122878, same trouble. I have canceled FileHistory then reactivate it, which results in error 0x8007000E.
So no more FileHistory on my PC... which used to work fine until now.
And no message about the trouble in event manager.
I am using W10 (french) Version 22H2, OS 19045.7725

You can ask a question.
I'm having the same problem. Very annoying. I have tried all the fixes I've researched on line, but nothing works. It seems the only alternative is to uninstall my last update, whichI really don't want to do. I hope microsoft pushes out a fix to this problem!
Having the same or similar problem
