Microsoft reassured Windows 11 and Windows 10 users that their PCs will continue to boot normally and receive updates even if they have not yet received the new Secure Boot 2023 certificates. The rollout of these certificates is expected to continue over the upcoming months. The initial Secure Boot certificate expired on June 24, 2026, and Microsoft has been replacing older 2011 certificates since 2024. The latest update, KB5101650, transitioned Windows 11 to OS builds 26200.8875 and 26100.8875 for versions 25H2 and 24H2, respectively. The 2023 certificates replace older certificates with modern cryptographic standards, allowing Microsoft to deliver DBX revocation updates without interruption. Devices using the 2011 KEK can only receive DBX updates signed with that key, which is no longer valid after June 24. Microsoft has been rolling out the 2023 certificates for the past two years, and many devices remained in a yellow or red status by the June deadline. To check Secure Boot status, users can navigate to Windows Security > Device Security. A green checkmark indicates successful application of the certificates, while yellow and red alerts indicate compatibility issues or firmware incompatibility. PCs that are older or operating in Legacy BIOS mode will not receive the updates. Windows 10 also receives Secure Boot updates, but enrollment in Extended Security Updates (ESU) is required.

Microsoft is introducing the KMS Hardware Secured system to enhance Windows licensing security by making unauthorized activation methods more difficult. This system will use TPM-based attestation to authenticate the server managing activation requests, ensuring only legitimate devices are recognized. Readiness notifications for Windows Server 2025 will begin in August 2026, allowing administrators to prepare for the transition to TPM-based attestation, which is expected to become a requirement for KMS activation in a future Windows Server release. This initiative targets corporate clients using Windows volume licensing to complicate unauthorized activation. Additionally, Microsoft plans to reduce its workforce by approximately 4,800 positions, or nearly 2.1% of its global staff, as part of a corporate transformation strategy.

McAfee offers features such as file scanning, network traffic filtering, VPN services, and browser warnings to protect users. Users can pause Real-Time Scanning by opening the McAfee app, selecting Real-Time Scanning under My Protection Widgets, and turning it off. To disable the Advanced Firewall, users must access the Advanced Firewall section in the app and turn it off. Scheduled scans can be stopped by navigating to Scheduled Scans in the app and clicking Turn off. To prevent Secure VPN from reconnecting, users can toggle it off in the Home tab and set Auto Connect to Never connect automatically. Browser protection features can be managed by toggling off McAfee WebAdvisor in Chrome, Edge, and Firefox. Users can block fake McAfee popups by adjusting notification settings in their browsers. To prevent McAfee startup helpers from opening, users can manage startup settings in Windows. To completely remove McAfee, users should uninstall it through Settings or Control Panel and follow the prompts. If remnants remain, the MCPR tool can be used for complete removal. Microsoft Defender will reactivate automatically after McAfee is uninstalled.

Microsoft has mandated the inclusion of the Trusted Platform Module (TPM) as a standard feature in all new motherboards and CPUs to enhance the Windows activation process. The company has introduced an enhancement to its Key Management Service (KMS) that leverages TPM's security capabilities to authenticate the legitimacy of KMS servers. This new "TPM-based attestation" aims to mitigate exploitation risks associated with KMS by validating the cryptographic integrity of KMS servers. Starting in August 2026, TPM-based attestation will be required for KMS activation with the next release of Windows Server. Microsoft has also closed off the "KMS38" activation method in 2025, while traditional KMS activation remains functional. The Massgrave collective has developed an Online KMS method that may be impacted by the new TPM-based attestation.
