Microsoft will begin automatically enabling its Memory Integrity security feature on a broader range of eligible Windows PCs through quality updates starting in October 2026, extending the kernel-level protection to more existing devices by default. In a September 1 blog post, Microsoft said the rollout will provide stronger protection for more devices against attacks targeting the Windows kernel, while PCs that already have Memory Integrity deliberately disabled will retain their existing configuration.
“Windows quality updates will begin enabling memory integrity protection on eligible devices,” Microsoft said. The updates will also enable Virtualization-based Security (VBS) where required, which provides the isolated environment underlying Memory Integrity. Before making the change, Windows will automatically assess each device using what Microsoft describes as readiness signals covering its hardware capabilities, compatibility, and performance.
