Windows and Linux users: The deadline to update Secure Boot keys is near

In 2012, a novel bootkit targeting Mac OS X systems emerged, infiltrating the EFI firmware. A basic bootkit for Windows 8 also appeared, compromising the UEFI bootkit. By 2013, a more sophisticated UEFI bootkit named Dreamboat was introduced for Windows. The first documented real-world UEFI attack occurred in 2018 with the malware LoJax, linked to a Kremlin-backed hacking group. In 2020, the second known UEFI malware, MosaicRegressor, was discovered, which verified the presence of a malicious file upon each reboot. New UEFI bootkits like ESpecter, FinSpy, and MoonBounce have since emerged. In response to the threat of UEFI bootkits, Microsoft collaborated with manufacturers to implement Secure Boot, a protocol that uses cryptographic signatures to ensure the integrity of firmware during startup.

Microsoft released the Windows 11 Secure Boot update for all PCs, how to verify yours

Microsoft has expanded the rollout of the Secure Boot 2023 certificate update to more Windows 11 and Windows 10 devices with the June 2026 Patch Tuesday update (KB5094126). This update aims to ensure that most supported consumer PCs are classified as high confidence, meaning necessary certificates are either installed or will be applied automatically. Secure Boot is a firmware security feature that verifies the software attempting to load during the startup process, blocking unauthorized software. The certificates supporting Secure Boot, issued in 2011, are expiring in stages starting June 24, 2026, prompting Microsoft to deploy replacement certificates. Most home users do not need to take manual action as the updates will occur automatically via Windows Update. Users can check their Secure Boot certificate status in the Windows Security app. A yellow warning indicates pending compatibility data, while a red alert suggests a firmware incompatibility requiring a BIOS update. Multiple reboots during the update process are normal, and a new SecureBoot folder in Windows is for staging cryptographic files. Older PCs may experience longer update times, and some may not receive updates due to firmware issues. HP users should check for BIOS updates if encountering BitLocker recovery loops. IT administrators should monitor device classifications and manually initiate updates for devices not in the high confidence category. Devices with Secure Boot disabled cannot receive updates, leaving them vulnerable. The expiration of the Microsoft Corporation KEK CA 2011 certificate on June 24 does not immediately affect device functionality, but it limits Microsoft's ability to sign new bootkit blacklist updates.

FAQ: What you need to know about expiring Windows Secure Boot certificates

Secure Boot is a security mechanism that authenticates firmware-based software through trusted certificates during the startup process of Windows, preventing unauthorized code execution. It is part of the UEFI firmware standard and was introduced in 2011 to allow only verified, signed code to run at startup. Microsoft first implemented Secure Boot certificates in 2011 as an optional feature in Windows 8, and it remained optional in Windows 10. However, it became a mandatory requirement with the launch of Windows 11 in 2021, indicating the widespread adoption of UEFI systems.

Windows Security App Gains Secure Boot Certificate Status Ahead of Major Certificate Refresh

The Secure Boot certificates used by the Unified Extensible Firmware Interface (UEFI) on Windows PCs will expire in late June 2026. Microsoft is rolling out updated certificates through Windows Update to ensure user protection. Starting in April 2026, users can check their device's status in the Windows Security app, which will feature a color-coded badge system: - Green Checkmark: New certificates are installed, no action needed. - Yellow Caution Badge: Update pending or blocked due to hardware/firmware issues (expected in May 2026). - Red Stop Icon: Alerts users that older certificates are expiring, potentially preventing essential boot-level security updates (may appear as early as June 2026). The status will also be indicated in the Windows Security system tray icon. Most users will have a seamless update process by keeping Windows Update enabled, with devices from 2025 and many from 2024 covered. Older machines will receive updates gradually, guided by major OEMs. Microsoft advises against ignoring yellow or red warnings, as devices without updated certificates may be vulnerable to security threats and incompatible with future Windows updates. A support resource is available at aka.ms/getsecureboot.

Microsoft’s Secure Boot certificates expire in June 2026, but older PCs may never get the fix

Every Secure Boot-enabled Windows PC relies on cryptographic certificates issued by Microsoft in 2011, embedded in the motherboard's firmware, to ensure a secure boot process. The first of these certificates will expire on June 24, 2026, which will affect the ability to receive future security updates for critical components of the Windows startup process. Microsoft is rolling out replacement certificates through Windows Update, marking a significant security maintenance effort. Secure Boot operates as a chain of trust with certificates stored in the motherboard's UEFI firmware, validating software before the operating system loads. The Platform Key (PK) is at the top of this chain, followed by the Key Exchange Key (KEK) and the Signature Database (DB). The replacement certificates introduced in 2023 restructure certificate management, separating responsibilities among different certificate authorities to enhance the trust model. Not all PCs are affected by the upcoming expiration; newer devices manufactured since 2024 already have the new certificates. Windows 10 users face challenges as support for this version ends in October 2025, and they will not receive the new certificates unless enrolled in Extended Security Updates. Home users should ensure their PCs are set to receive updates automatically, while enterprise environments require coordination for firmware updates before the Windows certificate update.
