Windows 11’s last Secure Boot deadline is weeks away, here’s what you must do

Microsoft is continuing the rollout of Secure Boot certificate updates, with the next significant deadline on October 19, 2026, when the Microsoft Windows Production PCA 2011 certificate expires. The September 2026 Patch Tuesday update has expanded eligibility for Secure Boot certificates to more PCs classified as “high confidence.” Users may need to reboot their PCs to install these updates, and some may require firmware updates beforehand. Microsoft has confirmed that the update process will persist beyond established deadlines, and older certificates are expiring in stages, with the first two deadlines having already passed. Users should ensure they have the latest updates installed and check their Secure Boot status in Windows Security. Microsoft has assured that PCs without the newer certificates will continue to boot normally and receive standard updates while the rollout continues.

Microsoft releases Windows security update addressing 723 flaws

Microsoft released its September 2026 security updates, addressing two critical Windows elevation-of-privilege vulnerabilities: CVE-2026-85880 and CVE-2026-81963. Both vulnerabilities were exploited before their public disclosure on September 8. CVE-2026-85880 involves a heap-based buffer overflow in the Windows Advanced Local Procedure Call (ALPC), allowing low-privileged attackers to gain SYSTEM privileges. CVE-2026-81963 affects the Windows Update Stack due to improper link resolution and access controls, enabling similar privilege escalation. The September release also includes 974 Common Vulnerabilities and Exposures (CVEs) across various Microsoft products, with 723 affecting Windows. Users of Windows 11 24H2 and 25H2 receive updates via KB5124008, while Windows 11 26H1 receives KB5124012. Windows 11 24H2 Home or Pro editions will reach end of servicing on October 13, 2026. Users are advised to install the updates promptly and back up important data.

Windows 11 wants your trust. Microsoft keeps testing it

Microsoft is facing significant security and reliability issues, particularly related to system startup, BitLocker recovery, and updating Secure Boot certificates. Users have expressed confusion over these complexities, especially regarding Microsoft Defender Antivirus errors. These problems stem from a tumultuous period before the launch of Windows 11, including changes to the TPM requirement and the extension of Windows 10's life. Despite increased security patches, underlying issues remain, leading to user skepticism about the reliability of Windows systems.

I’ve Been Gaming On Linux For Five Years – Is It Ready To Replace Windows?

Steam Deck debuted in early 2022 with SteamOS, a Linux-based operating system that uses the Wine-based Proton compatibility layer to run Windows games. This development has significantly advanced Linux gaming, with approximately 95% of games functioning well on Linux. Steam's Verified program lists nearly 9,000 Verified games, and around 30,000 playable titles, with only about 1% of popular games failing to run entirely. Anti-cheat systems remain a major limitation, preventing popular titles like "Fortnite" and "League of Legends" from being playable on Linux. Game streaming services like NVIDIA GeForce NOW offer alternatives for playing anti-cheat games on Linux. Linux distributions provide better controller support compared to Windows, particularly for handhelds and living room PCs. Accessing non-Steam games can be cumbersome, though tools like Heroic Launcher help. Compatibility issues with proprietary standards, such as HDMI 2.1 support, persist in Linux gaming.

Nvidia: Windows 10 drivers for GeForce end in 2026

Nvidia will stop regular support for Windows 10 drivers for GeForce graphics cards by October 2026, after which users will receive only quarterly security updates until October 2029. The last Game-Ready driver for Windows 10 will be released in October 2026, with the first driver lacking Windows 10 support scheduled for November 2026. Modern GeForce RTX graphics cards will not receive new drivers if running on Windows 10 after October 2026. Nvidia's support for older architectures like Maxwell, Pascal, and Volta will end in October 2025, with quarterly updates until October 2028. Users are encouraged to transition to Windows 11, as Microsoft will conclude general support for Windows 10 on October 14, 2025. Users should check hardware compatibility for Windows 11, including TPM 2.0 and Secure Boot. The last regular driver version for Windows 10 will remain available after October 2026, but Nvidia will not be obligated to address routine bugs or compatibility issues thereafter.

Microsoft is updating Windows Production CA, IT admins and devs should take action ASAP

Microsoft is updating its Windows certificate framework, focusing on Secure Boot certificates and the expiration of certain Windows 11 Insider certificates. A new certificate update is crucial to prevent disruptions in applications and IT processes. Microsoft is phasing out outdated certificates and modernizing signing algorithms, with the Windows Production Public Certificate Authority (PCA) 2011 set to expire on October 19, 2026. It will be replaced by a new PCA, and stronger signing algorithms like RSA-3072 and SHA-384 will be adopted later this year. Applications relying on outdated technologies may fail due to these updates. IT administrators and application developers are advised to review software, adopt algorithm-agnostic approaches, test certificate changes, and check private trust stores for issues. The timeline includes the PCA expiration in 2026, a transition to stronger configurations later that year, and a default to post-quantum cryptography (PQC) in 2027, with ongoing updates as security needs evolve.

Modern Warfare 4 team “hard at work” to improve PC optimization and mouse controls, as players express beta frustrations

The beta phase for Call of Duty: Modern Warfare 4 has started, facing performance issues, especially for PC gamers who report input delays with mouse and keyboard setups and a perception that multiplayer favors controller users due to aim assist. Activision and Infinity Ward are working to improve the PC experience, focusing on customizable settings, mouse input responsiveness, and a preload feature for shaders. Some players are frustrated with the game's requirements for Secure Boot and TPM 2.0, which may not be recognized even after installation. An update is planned to address footstep audio, map voting, weapon balance, and bug fixes. The beta currently has a 53% positive rating on Steam, with concerns about movement mechanics and map sizes affecting gameplay.

Microsoft’s Windows 10 cutoff could push 400 million working PCs toward e-waste heap

Microsoft will end standard support for Windows 10 on October 14, 2025, affecting an estimated 400 million PCs that may not meet the new eligibility criteria for Windows 11, which include TPM 2.0, UEFI Secure Boot, and modern processors. This could lead to a potential increase of 1.6 billion pounds of electronic waste if these devices are discarded. Users may need to invest in new hardware or alternative operating systems, despite their current machines still functioning adequately. Microsoft offers an Extended Security Updates program until October 12, 2027, and Windows 10 IoT Enterprise LTSC, which will be supported until January 2032. Users can also consider transitioning to Linux or ChromeOS Flex for older computers.

Windows 11 KB5121003 is triggering game crashes and other issues on some PCs

Windows 11 update KB5121003, released in August 2026, addresses over 400 vulnerabilities but has caused crashes in games like ARC Raiders and The Finals. The game studio Embark has confirmed that the crashes are linked to the inpoutx64.sys driver, which has compatibility issues due to the update. Users have reported errors such as “Hang detected on GameThread” and “EXCEPTIONACCESSVIOLATION” after installing the update. Embark has provided a workaround to stop and delete the inpoutx64.sys service to resolve the crashes. Uninstalling the update also appears to fix the issue. Additional reports indicate crashes in other games and graphics-related problems following the update.
