KB5101684/KB5120249 caused File History errors, but Microsoft has not acknowledged them.

Acer laptop (Windows 11 25H2, LAPTOP-GJTRIQFJ, Nitro AN515-57)

desktop (Windows 10 22H2, 202108, Acer PC Aspire M1935)

I recently posted on Microsoft Learn, Reddit, and Microsoft Community Hub that after these two updates, my file history log is abnormal. I can successfully back up the D drive, but the backup time is not synchronized. Since my post, 10 other users have encountered the same problem. I hope Microsoft can quickly confirm and fix this issue and release a security patch. I have also reported and inquired about this issue through the Windows 10 22H2 Feedback Center, but have not received any response so far. Have you seriously investigated this update causing the file history log problem? I have reported this issue and provided detailed information from two different computers. If Microsoft does not investigate and confirm whether the recent update caused this problem, and does not provide a fix in future security updates, I will have no choice but to continue reporting this issue through all available official channels and urge other affected users to do the same.

I sincerely suggest that Microsoft either silently fix this issue in the end-of-August preview update or the September-October security patch, or include a fix for this file history log problem in the August-October update. If this isn't confirmed and resolved, I and other affected users have been extremely frustrated and annoyed for the past two months.

If you've encountered the same problem, don't worry, feel free to leave a comment below or ask a question on the Microsoft Community Hub or Microsoft Learn.

    Despite the large number of user reports from places like the Microsoft Q&A forum, Microsoft has not officially listed this specific problem as a known issue for either KB5101684 or KB5120249. They did officially acknowledge a different File History bug in April 2026 (related to SMB network backups), and KB5120249 was actually released to fix SMB backup problems.

      I've asked in Microsoft Q&A and Reddit multiple times, and others have also told me they've encountered similar issues.
