The BigFix Patch Team is pleased to announce the release of new content in
the *Patches for Windows* site to support the assessment and renewal of
Microsoft Secure Boot Certificates.

*Background*
Starting in June 2026, the three original Certificate Authorities (CAs)
provided by Microsoft for Secure Boot (KEK CA 2011, Windows Production PCA
2011, and UEFI CA 2011) will begin to expire. To maintain Secure Boot
functionality and ensure devices can continue to receive security updates
for boot components, systems must be updated to the new 2023 certificates.

*What is Included*
1. Assessment: Microsoft Windows Secure Boot Inventory Data

   - Analysis ID: 660
   - Site: Patches for Windows
   - Details: This analysis allows you to monitor the transition and verify
   the Secure Boot status across your environment. It retrieves critical data
   points including UEFI CA 2023 Status, Error codes, Secure Boot enablement,
   and OEM-specific firmware details.


2. Remediation: Windows Secure Boot certificate expiration and CA updates

   - Fixlet ID: 506820201 (KB5068202)
   - Site: Patches for Windows
   - Details: This Fixlet automates the registry configuration
   (`AvailableUpdates` set to `0x5944`) required to signal Windows to execute
   the certificate update.
   - Action: The Fixlet includes two actions, both of which require a
   **reboot** to complete the firmware-level update process.


*Important Deployment Notes*

   - *Test Before Mass Deployment*: Because this process involves
   firmware/UEFI variables, we strongly recommend testing this content on
   representative hardware models in your environment before a broad rollout.
   - *OEM Compatibility*: Please consult your Original Equipment
   Manufacturer (OEM) documentation to ensure your hardware supports these
   Secure Boot updates.
   - *Success Criteria*: Once the Fixlet is applied and the system is
   rebooted, the `UEFICA2023Status` (tracked via Analysis 660) should
   transition from `NotStarted` to `Updated`.
