Baseline Month
Note
The October 2026 Windows security update will be released as a standard update rather than a hotpatch update. Some of the security improvements in this update change components that cannot be updated without a restart. As a result, devices enrolled in hotpatching will need to restart to complete installation.
The October 2026 security baseline will be available starting October 13, 2026. For more information, see KB5127648.
To learn more about release cadence, see the release notes for Hotpatch on Windows 11 Enterprise, version 25H2 and version 24H2.
