Windows Server administrators should update Secure Boot certificates before the June 2026 expiration date. Microsoft has held Secure Boot Ask Microsoft Anything (AMA) sessions in December 2025 and February 2026, with recordings available for those who missed them. Upcoming AMAs are scheduled for March and April. Administrators are encouraged to follow Windows Events on the Microsoft Tech Community and bookmark the Windows Secure Boot certificate updates page for centralized guidance and resources.
