Windows update patches a whopping 1,400 security bugs –  including 2 zero days

Microsoft released the October Windows update, addressing over 1,400 vulnerabilities, including 80 critical vulnerabilities and two zero-day exploits. This update is the final supported update for Windows 11 24H2 Home and Pro editions and the first for Windows 11 26H2. Notable enhancements include improvements to File Explorer and refined Bluetooth connectivity. One zero-day vulnerability, CVE-2026-96951, has been exploited in the wild, allowing remote attackers to bypass security protections. The second zero-day, CVE-2026-108398, could enable attackers to circumvent security measures in Microsoft’s .NET Framework. Windows 11 users can install the update via Settings and Windows Update, while Windows 10 users can follow a similar process. Each annual version, such as 24H2, will lose support after 24 months, necessitating an upgrade to Windows 11, version 26H2, for continued security updates. The update also introduces a feature to remap the Copilot key for enhanced user flexibility.

Windows 11 26H2 gave my laptop nearly 2GB of RAM back, but there’s a catch for low-RAM PCs

Windows 11 version 26H2 has been released, resulting in a decrease in RAM usage for many users. Reports indicate that users with 16GB or more of RAM have experienced reductions in idle memory usage, with one user noting a drop from 6.9GB to approximately 4.8GB, and another from over 10GB to about 7GB. However, users with 8GB of RAM have not reported similar improvements, leading to concerns that this update primarily benefits those with larger memory capacities. Personal tests on a laptop showed a decrease in idle memory usage from 8.5GB to 6.7GB after the update. Despite Microsoft's commitment to optimizing memory usage, the 8GB machines have not seen the same enhancements.

NVIDIA Freezes Windows 10 GeForce Drivers in October: RTX 40-Series Misses DLSS 5 Support

On October 14, 2026, NVIDIA will release the final GeForce Game Ready Driver for Windows 10, coinciding with the operating system's mainstream end of support. Starting in November 2026, all new Game Ready and Studio Driver releases will only support Windows 11. Approximately 23.56% of Steam gamers were still using Windows 10 as of June 2026. The last Game Ready driver for Windows 10 is version 617.42, released on October 6, 2026. NVIDIA will provide quarterly security updates for Windows 10 GeForce drivers until October 2029, but no new game support or enhancements will be available. Users with RTX 20, 30, 40, and 50 series cards will be affected by this transition, while older models like the GTX 900 and GTX 10 series have already reached their support limits. Windows 10 users will miss out on DLSS 5, which is exclusive to RTX 50-series hardware. Microsoft has extended the free consumer Extended Security Update (ESU) program for Windows 10 to October 12, 2027.

GLM’s 23 Windows Bug Finds Are Z.ai Building a Security Research Resume

Z.ai's GLM model identified 23 vulnerabilities in the Windows operating system, confirmed by Microsoft's Security Response Center (MSRC). This marks a significant advancement in commercial software security, demonstrating the model's autonomous capability in independent vulnerability discovery. Since the release of GLM-5.2, Z.ai has uncovered over 4,200 vulnerabilities across about 390 open-source projects, with over a thousand categorized as critical to high severity. Z.ai has established a public Security Disclosure Ledger to track its findings through a coordinated disclosure process. The confirmation of vulnerabilities by MSRC is notable due to the rigorous nature of their vulnerability triage operations. Z.ai's GLM-5.3 achieved a score of 84.5% on CyberGym, outperforming competitors like Anthropic's Mythos 5 and OpenAI's GPT-5.6 Sol. Reports indicate that NIST's AI safety division has flagged GLM-5.3 due to concerns about its cyber capabilities, particularly regarding the potential for modified versions to reduce safety features. Z.ai plans to continue targeting commercial software in its efforts.

Microsoft admits a Windows 11 bug is causing stutter in games, and it’s not your mouse or drivers’ fault

Microsoft released the October 2026 Patch Tuesday update (KB5127648) for Windows 11, which fixes a mouse input stuttering bug affecting certain games. This issue was acknowledged in the release notes, stating that the update resolves the stuttering problem. The fix was not included in the optional preview released on September 22. While specific causes and affected games were not disclosed, anecdotal evidence suggests the problem originated from Windows itself. Users reported erratic mouse behavior in games like Star Wars: The Old Republic and Final Fantasy XIV, with persistent issues even after trying various fixes. The update brings Windows 11 versions to Build 26300.9711 for 26H2, Build 26200.9711 for 25H2, and Build 26100.9711 for 24H2, marking the final release for Windows 11 24H2 Home and Pro. An offline installer is available for those having trouble with Windows Update. If stuttering continues, users are advised to check for outdated drivers or other potential issues.
