Microsoft tells crusty old kernel drivers to get with the Windows Hardware Compatibility Program

Microsoft is enhancing the security of the Windows kernel by eliminating trust for kernel drivers not certified through the Windows Hardware Compatibility Program (WHCP) starting with the April 2026 Windows Update. This change specifically targets kernel drivers signed by the now-obsolete cross-signed root program, which has been associated with security vulnerabilities. The new policy will initially be introduced in an "evaluation mode" to monitor and audit driver loads for potential compatibility issues. Custom kernel drivers can still be used under the Application Control for Business policy, but must be signed by an authority within the device's Secure Boot Platform Key or Key Exchange Key variables. The changes will impact Windows 11 versions 24H2, 25H2, 26H1, and Windows Server 2025.

Windows 12 Forecast Six Expert Predictions

Microsoft is preparing for the release of Windows 12, which is expected to feature an AI-native experience with deep integration of Copilot, showcasing capabilities like on-screen comprehension, voice activation, and task automation. The hardware requirements will be elevated, necessitating 16GB of RAM, rapid NVMe storage, and a Neural Processing Unit (NPU) for advanced features. Windows on Arm is gaining momentum, with improvements in app compatibility and battery life, while a modular architecture called CorePC is being developed to facilitate faster updates and enhance security. Licensing for Windows 12 is expected to remain unchanged for consumers, with optional cloud-enhanced services available. The update cadence will increase, allowing for faster feature drops independent of major OS releases, with the Windows Insider Program continuing to test new features. Upon its release, Windows 12 will integrate Copilot, provide a more cohesive OS core, and support both x86 and Arm architectures.
