Windows 11 2025 version 25H2: Microsoft has officially released its annual operating system update
Microsoft has officially released its annual operating system update, Windows 11 2025 (version 25H2). The update is primarily focused on internal enhancements and cybersecurity, notably introducing significant advancements in vulnerability detection—both at compilation and runtime—and incorporating AI-assisted secure coding. The company states that the 25H2 version is specifically designed to "address and mitigate security threats," adhering to its Security Development Lifecycle (SDL) requirements.
The update is now available as an enablement package (eKB) through Windows Update for eligible devices running Windows 11 24H2. Both the 24H2 and 25H2 versions utilize a shared codebase and servicing branch, a structure that streamlines the update process and enables the continuous delivery of new features via monthly updates. Microsoft is delivering the update via servicing technology for a fast and reliable installation experience.
The company will implement a security hold to defer the update for devices where application or driver incompatibilities are identified until the issues are resolved.
