Files are backed up, but File History status and Previous Versions are not updating after recent Windows updates KB5101684 and KB5120249

Hello,I would like to ask whether anyone else has noticed unusual behavior with File History on Windows 10 or Windows 11 following recent updates.

I noticed this on two separate computers:

Windows 11 25H2 — KB5101684, installed July 29, 2026

Windows 10 22H2 — KB5120249, installed August 12, 2026

The backup files are still being written to my D: drive, so the backup process itself appears to be running. However, File History does not properly reflect the latest backup status, and Previous Versions does not show the newly backed-up versions of files.

Facing netizens EmilyS726 question, For clarity, I also want to address concerns about previous system changes. I made some changes to User Shell Folders, Music/Videos folders, and OneDrive folder redirection in 2025 and June 2026. These changes did not interfere with File History at the time. File History continued to work normally, including updating the backup time.

Other netizens have had similar experiences, but it's definitely not due to modifying the registry. I haven't modified the registry either.

I did not make any relevant changes immediately before installing KB5101684 or KB5120249. The behavior changed only after those updates were installed.

Interestingly, I found that selecting the backup drive again can temporarily restore normal behavior:

Control Panel → File History → Select drive → select the D: drive again

After this, File History begins updating normally again.

Because I have now seen essentially the same behavior on two different systems following two separate updates, I am wondering whether there may be a common Windows component or a recent regression involved.

I have already submitted a report through the Feedback Hub, but have not received a response.

If you have noticed anything similar, especially after either of these updates, please share your experience. It would also be helpful if Microsoft could determine whether these updates have affected File History functionality.

Thank you.

Hi, thank you for the detailed information.

Since the backup files are still being created on the D: drive, File History itself appears to be working. The issue seems to be that the File History status and Previous Versions are not refreshing correctly after the updates.

Please try this first:

Control Panel → File History → Select drive → select your D: drive again → Save

This will re-register the backup drive and may refresh the File History database.

If the issue comes back, try rebuilding the File History configuration:

  1. Press Win + R, type services.msc
  2. Find File History Service (fhsvc) and stop it
  3. Delete this folder: C:\Users\YourUserName\AppData\Local\Microsoft\Windows\FileHistory
  4. Re-enable File History and select the backup drive again

Your test on both Windows 10 and Windows 11 suggests this may be related to a Windows update regression rather than User Shell Folders or OneDrive folder redirection changes.

Please continue reporting it through Feedback Hub with the File History logs if possible: Event Viewer → Applications and Services Logs → Microsoft → Windows → FileHistory-Engine.
