Updates for Windows 11 23H2
As for Windows 11 version 23H2, Microsoft has released KB5075941, which raises the OS to Build 22631.6649. Both of these updates come packed with this month’s security patches and also include some “non-security updates” from the previous optional preview release, depending on the version track you’re on.
Important Secure Boot Information
In the release notes for the two updates, Microsoft has highlighted a critical upcoming deadline for Secure Boot maintenance. The Secure Boot certificates that are utilized by most Windows devices are set to begin expiring in June 2026. Microsoft cautions that devices might face issues “if not updated in time” and directs users and organizations towards its guidance for Secure Boot preparation.
On the 24H2/25H2 versions, Microsoft has stated that it is using this month’s servicing to further its phased rollout strategy. The quality updates for Windows now include targeting data that helps identify which devices are ready to receive new Secure Boot certificates, with the certificates being distributed only after there are “sufficient successful update signals.”
Fixes and Improvements in Updates
Within KB5077181, Microsoft points out several fixes, including resolving a full-screen gaming eligibility problem and addressing a bug that could prevent connections to certain WPA3-Personal Wi-Fi networks following a previous update. They have also announced that updated AI components (Image Search, Content Extraction, Semantic Analysis, and a Settings Model) are now at version 1.2601.1268.0, as detailed in the release notes.
At the time of writing, Microsoft has indicated that it is not aware of any issues with KB5077181.
For the Windows 11 version 23H2 update, Microsoft has mentioned a change regarding Secure Boot/Boot Manager: on devices that already have the Windows UEFI CA 2023 certificate within the Secure Boot signature database (DB), the update will replace the older 2011-signed bootmgfw.efi with the 2023-signed version. They also warn that resetting the DB or toggling Secure Boot could lead to a “Secure Boot violation” and notes that recovery media is a potential solution in rare cases.
Additional Fixes in KB5075941
KB5075941 also addresses a commonly discussed problem where some computers using Virtual Secure Mode (VSM) might restart instead of shutting down or entering hibernation after receiving security updates from January 13, 2026, onwards.
Similar to the package for 24H2/25H2, Microsoft asserts that there are no known issues with KB5075941 at the time of this publication.
