Broken File History after July/August Updates (KB5101684 on Win11 25H2 / KB5120249 on Win10 22H2)

Hi everyone,

I am writing to report a major regression bug with File History that was introduced in the recent Windows updates. This is happening across two entirely different machines with no settings changed, no system files modified, and no registry tweaks applied.

The Issue:

Windows 11 25H2 > after installing KB5101684 (July 29, 2026)

Windows 10 22H2 > after installing KB5120249 (August 12, 2026)

On both PCs backing up to a local drive (D:), the underlying files are actually being written to the drive, but the File History interface is completely broken:

TheLast Backup time stamp in Control Panel frozen and fails to update automatically.

In File Explorer, right-clicking new files > Properties> Previous Versions shows There are no previous versions available, making daily time-travel restoration impossible.

Temporary Workaround:

The only way to force it to sync is to go to Control Panel > File History > Select Drive, and re-select the D: drive again. This proves the backup engine works, but the automatic scheduling and catalog syncing are completely frozen by these updates.

Please Help Upvote on Feedback Hub:

I have already submitted this issue via the Feedback Hub but have received no official response yet. Since File History is critical for users who prefer local offline backups over OneDrive, we need to bring this to Microsoft’s attention immediately so they can patch it in the next cumulative update.
