Code integrity checks run inside a secure, hypervisor-managed container. Even if an attacker gains administrative privileges in the main OS, they cannot modify the kernel execution policies.
Last updated: October 2025. Applies to Windows 11 version 22H2 (build 22621) and Windows Server 2022. kernel os 22h2 verified
Conclusion Windows 22H2 continued incremental hardening of the NT kernel through improved code integrity enforcement (HVCI/VBS), stricter driver signing, storage and networking stack enhancements, and performance/stability fixes driven by telemetry and Insider feedback. Verifying a "22H2" kernel installation involves cryptographic signature checks, hash baselining, platform firmware settings (Secure Boot), enabling virtualization-based protections, and active monitoring with Driver Verifier, ETW, and kernel debugging tools. stricter driver signing
