About this tag
The kernel driver trust tag covers Microsoft's ongoing changes to how Windows verifies and loads kernel-mode drivers, with a focus on security hardening and enterprise compatibility. Discussions center on the April 2026 policy that stops loading legacy cross-signed drivers by default, while maintaining a curated allow list and offering an evaluation mode for testing. Also covered is the WHCP driver policy pilot in Windows 11 Insider Preview Build 26220.8062, which tests stricter driver signing requirements. Recurring themes include the balance between security improvements and real-world ecosystem compatibility, the transition away from legacy trust paths, and the staged rollout approach Microsoft uses for these kernel trust changes.
