Microsoft to Enable Windows 11 Memory Integrity Feature, Potentially Affecting Gaming Performance

Microsoft is preparing to roll out its memory integrity security feature to more Windows 11 devices next month. The kernel‑level protection stops malicious code or drivers from running, but the company warned it can also reduce PC gaming performance. Windows quality updates will begin enabling memory integrity on eligible devices, and if not already active, will also activate Virtualization‑based Security (VBS). Gamers may need to disable the feature or wait for performance patches as the update spreads across the Windows ecosystem.
