kernel driver signing

About this tag
Kernel driver signing is a critical security mechanism in Windows that ensures only trusted, verified drivers can load into the operating system kernel. Recent threads on WindowsForum.com discuss Microsoft's tightening of kernel-mode trust policies, particularly the end of legacy cross-signed drivers by default on Windows 11 and Windows Server 2025. This change shifts the signing model toward the Windows Hardware Compatibility Program (WHCP) and modern security expectations. The policy aims to reduce the attack surface from unsigned or repackaged drivers, which are common vectors for privilege escalation and malware. Users and IT administrators are advised to verify driver signing status and test compatibility using evaluation modes before enforcement deadlines.
