secure boot update

About this tag
Secure boot update content on WindowsForum.com covers Microsoft's ongoing Secure Boot certificate chain refresh, particularly the transition to CA 2023 certificates ahead of the June 2026 expiry. Threads discuss how cumulative updates like KB5079473, KB5077179, and KB5094127 deliver these certificate updates and boot manager binary swaps. A recurring theme is the collision between Secure Boot updates and BitLocker recovery key prompts, especially on Windows 10 systems with specific Group Policy configurations. The updates are described as a multi-month, cross-industry operation to maintain boot security. Compatibility issues, boot delays, and driver conflicts are also reported. The tag primarily addresses enterprise IT administrators managing Windows 10 and Windows 11 devices.
