Microsoft has issued a fix for a known issue that was disrupting the built‑in File History backup feature on certain Windows systems after the rollout of the September 2026 security updates.
The bug, which prevented users from creating or restoring File History backups, had been reported by a number of Windows users following the recent update cycle. It affected a subset of systems, leaving many unable to rely on the feature for routine file protection.
In response, Microsoft released a corrective update that restores full functionality to File History. The patch is available through the standard Windows Update channel and is intended to resolve the backup failure on all affected devices.
Users who have experienced problems with File History after installing the September 2026 security updates are advised to check for the latest update and install it promptly to regain reliable backup capabilities.
