Microsoft Fixes Broken Windows 11 Backup Feature
The tech giant has released an optional update to resolve the issue with File History, which was introduced in the September update, with a full fix expected in October
Microsoft has admitted to breaking the File History backup feature in Windows 11 with its September update, but has since fixed it with an optional update. The bug, which prevented users from creating or updating backups, was first introduced in a July 2026 update.
The issue was caused by the September update, referred to as KB5124008, which affected users' ability to create or update backups using File History. Microsoft informed Windows Latest that some customers using File History might be unable to create or update backups after installing the September update.
The latest optional September update fixes the bug, but may not fully resolve all issues with File History. According to reports, the new update does allow File History to work again and make backups, but there still appears to be an issue with the 'Run now' ability and problems with synchronization of save times.
## What happens next The full fix for the File History bug is expected to be included in the October update, scheduled for release on October 13. This will provide a complete resolution to the issue, ensuring that users can once again rely on File History to keep their files backed up to an external drive or network location.
## Why it matters File History is a feature that enables users to keep files backed up to an external drive or network location, providing an essential layer of protection against data loss. Although it may not be widely used, it is crucial for those who rely on it to keep their files safe. The bug's impact on users' ability to create or update backups highlights the importance of regular updates and bug fixes to ensure the smooth operation of critical features like File History.
