An anomaly in File History logs has been reported by users after installing security update KB5101650. This issue impacts daily backups on multiple machines across different hardware configurations. The problem affects both Windows 11 and Windows 10 operating systems after specific cumulative updates. While physically copying files to the backup drive functions correctly, the File History interface shows an unchanged "Last Backup" timestamp. Newly created files are reported as having "No previous version available" in their properties. Additionally, automatic backup correction dates for some files and folders have been altered. A temporary workaround involves reselecting the backup drive within File History settings to force a logger restore. Users experiencing this exact problem are encouraged to report it and provide their system version information. This collective data aims to prompt Microsoft engineering for an official patch. The scope of this issue is currently being tracked by affected IT users.
