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.
