Microsoft: September updates break File History backup feature

Microsoft identified that File History, the built-in Windows backup feature, may fail on some systems after applying September 2026 security updates. The vendor has not yet released a fix but indicated it is investigating the issue.

Why it matters: Windows users relying on File History for backup protection face potential data loss if the feature stops working after patching, requiring immediate verification that backups are functioning.
