Windows 11 Secure Boot update released to all, hours ahead of expiry

Microsoft has begun rolling out the Secure Boot 2023 certificate update to eligible Windows 11 and Windows 10 PCs ahead of the expiration of the Microsoft Corporation KEK CA 2011 on June 24, 2026. This update enhances device targeting data for automatic Secure Boot certificate updates. Secure Boot is a firmware-level security feature that verifies digital signatures of boot components to prevent rootkits and bootkits. The certificates for Secure Boot were first issued in 2011, with subsequent expirations for related certificates occurring in June and October 2026. Users can check their Secure Boot certificate status through the Windows Security app or System Information. If a PC does not receive the update, it will still boot normally but will lose the ability to receive future boot-level security updates. Multiple restarts after updates are expected due to the Secure Boot certificate process. A new folder, C:WindowsSecureBoot, is not malware but is used for staging cryptographic certificate files. Windows 10 users enrolled in the Extended Security Updates program will also receive the Secure Boot update, while those not enrolled will not. The expiration of the KEK CA 2011 means Microsoft will not be able to sign new Secure Boot revocation payloads using the old key, but existing signed payloads will remain functional.

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.

Microsoft just broke some custom folder icons, and it’s deliberate

Windows 11 users have reported that their custom folder icons have reverted to default settings due to new security protocols from Microsoft. If a desktop.ini file, which defines folder icons, is detected as coming from an untrusted source, Windows will automatically revert to the standard icon without notification. Microsoft has confirmed that 'untrusted' icons will no longer display, and identifies scenarios that classify a source as untrusted, including files downloaded from the internet with a Mark-of-the-Web (MOTW), files copied from certain remote locations, and files on unrecognized network paths. To restore customizations, users can add the source to their Trusted Sites list, enable the "Allow the use of remote paths in file shortcut icons" policy, or remove the Mark-of-the-Web tag from affected files.
