code integrity logs

Code integrity logs on WindowsForum.com document how Microsoft's security updates block vulnerable kernel drivers, such as psmounterex.sys in the April 2026 update. These logs help administrators identify driver blocks that can break backup mounting and restore workflows. The recurring theme is that code integrity enforcement, while protecting against kernel-level attacks, may disrupt enterprise recovery processes that rely on outdated drivers. Discussions emphasize the need to audit code integrity logs to understand why specific drivers are blocked and to plan driver updates or workflow changes accordingly.
