Microsoft, which recently released the Windows11 26H2 update for the Windows operating system, has also rolled out the mid-October Patch Tuesday update to users. The Windows 10 KB5126657 update was released alongside important bug fixes. Details are in our article.
Microsoft has released the October 2026 Patch Tuesday update for Windows 10 users enrolled in the Extended Security Updates program. Cataloged as KB5126657, this update upgrades Windows 10 22H2 and 21H2 to build numbers 19045.7807 and 19044.7807, respectively.
The update provides permanent Daylight Saving Time (DST) support in Canada's British Columbia and Alberta provinces. It also introduces a new Manitoba Standard Time time zone, "(UTC-5:00) Manitoba".
What's new in the update?
Microsoft has added new auditing and policy controls for ReFS storage. Auditing on ReFS volumes attached to external storage devices is enabled by default, while enforcement controls remain off so administrators can assess and prepare.
The issue where Storage Spaces Direct virtual disks went offline following a Windows update has also been fixed. The issue was caused by valid tiered storage metadata being incorrectly treated as invalid during recovery, which prevented the affected virtual disks and dependent workloads from coming back online.
File History issue resolved
The issue where the File History app failed to back up or restore files to external drives or network locations has been fixed with this update. Affected devices incorrectly displayed the "Reconnect your drive" message even when a compatible backup drive was connected and functioning properly.
Meanwhile, Secure Boot certificates continue to be updated. Microsoft is using updated high-confidence targeting data to automatically prepare eligible devices to receive the new certificates. Rollout via Windows Update continues on all supported devices.
How can you install the update?
The KB5126657 update can be downloaded via Settings > Windows Update and through the Microsoft Update Catalog. According to Microsoft, there are no known issues resulting from this update. However, users will undoubtedly report any issues they experience through the forums.
