The September security update caused File History to malfunction for users of multiple Windows 11 versions and Windows 10.
A new optional preview update restores File History functionality for certain Windows 11 editions but not for Windows 10 or 23H2.
Users must manually install the preview update to fix the issue until a broader solution is provided in the next scheduled update.
THE READ
What the cluster adds up to.
The recent September Patch Tuesday update has introduced a bug affecting the File History feature in several Windows versions, preventing users from creating or running backups. Affected users may encounter errors indicating their backup drive needs to be reconnected, even when it is functioning correctly.
Microsoft has provided an optional preview update to address this issue for Windows 11 users, specifically targeting versions 26H1 and 25H2. Users need to manually download this update from the Windows Update settings to restore File History functionality.
However, this fix does not extend to Windows 10 or the 23H2 version of Windows 11, as Microsoft is still working on a solution for those systems. This limitation means that users on these older versions may remain at risk of data loss due to the bug until a formal fix is released in a future update.
