Microsoft Warns About Windows Update Certificate Expiration

Microsoft has reminded IT administrators about the expiration of certificates that enable trusted connections between Windows devices and Windows Update servers, set to expire in May and June of 2027. Devices without replacement certificates by these deadlines may lose access to Windows Update services. Most supported Windows devices will receive new certificates automatically through security updates, but older or infrequently updated systems may require manual intervention. Organizations that do not update their devices risk losing access to critical updates, particularly unsupported Windows versions that will not receive necessary certificate updates. IT teams should audit device inventories and ensure compliance with updates, as systems on supported versions will obtain replacement certificates seamlessly. Upgrading unsupported systems is essential, and organizations are encouraged to conduct audits and expedite upgrade projects to avoid losing access to Windows Update.

Microsoft discloses bug in Windows 11 September update causing apps using Dolby Digital to crash

On October 2, Microsoft announced that its optional preview update "KB5124010," released on September 22, causes crashes in applications using the Dolby Digital (AC-3) codec on Windows 11 versions 24H2, 25H2, and 26H2. The update does not include security fixes and affects media players, games, and certain line-of-business applications that rely on Windows' built-in AC-3 audio decoding. Symptoms include applications failing to launch or crashing during specific features like music playback. Users can check if they are affected by verifying their OS version, installed updates, and application implementation. Microsoft plans to address the issue in a future update, but a timeline is not provided. Users can uninstall KB5124010 or pause updates as temporary solutions.

Microsoft confirms Windows 11 26H2 is crashing some games and apps, promises to fix it in the next update

In October 2026, Microsoft is addressing ongoing issues from its September updates for Windows 11, particularly related to audio decoding. Certain applications and games using Windows' built-in AC-3 (Dolby Digital) audio decoding may crash when users adjust volume or audio settings. This issue primarily affects older applications and games, while most modern apps are expected to function normally. Microsoft has issued multiple updates, including a mandatory Patch Tuesday update and an emergency patch, but some audio problems remain unresolved. The September updates also introduced a significant increase in security fixes, addressing 974 vulnerabilities compared to 86 in September 2025. Additionally, an emergency update disrupted the functionality of File History, which Microsoft is investigating. An optional update aimed to fix File History but led to new crashes in various applications. Microsoft is currently working on a resolution for the audio-decoding bug without a specified timeline.

GrapheneOS Isn’t Happy With Google Over Pixel’s Widening Head Start

Google's September 2026 Pixel Update Bulletin includes patches that affect standard Android platform code, relevant to both Pixel and non-Pixel devices, which have not been included in the regular monthly Android Security Bulletin. GrapheneOS has noted that Android 17 QPR1 introduced new developer APIs not present in the Android Open Source Project (AOSP) for the first time since Android Honeycomb, with one new package and modifications to sixteen others. GrapheneOS is backporting Pixel firmware and drivers from QPR1 onto Android 17 but lacks permissions to distribute this work. Additionally, there has been a delay in Google’s compliance with a GPL source request, with access granted over two weeks after the initial request. Starting in 2027, Google will require all Android app developers to register with them and provide legal identification and signing key evidence, complicating the process of sideloading unverified apps. GrapheneOS and other organizations are advocating for the Keep Android Open campaign against these developments, which may restrict competition and tighten Google's control over the Android ecosystem.

That security patch date on your Android phone is no longer the full story

Google has launched the AndroidX Security State and Security State Provider libraries, enhancing Android's security framework. These tools allow applications to assess the security status of individual components on a device, rather than relying solely on the overall security patch level. Applications can now verify specific security fixes, identify available updates, and check for pending installations. This is particularly useful for security-sensitive applications, such as banking software, which can confirm the presence of necessary security fixes before allowing transactions. The libraries also enable apps to check for the resolution of specific vulnerabilities (CVEs), ensuring critical fixes are in place before enabling features like tap-to-pay. Phone manufacturers can communicate specific security fixes without changing the overall security patch date, meaning a device may show an outdated patch date while still having resolved certain vulnerabilities.
