Since the November 10, 2026 update KB5132061, Windows 11 25H2 and 26H2 can turn on Memory Integrity (HVCI) by itself on eligible PCs, as a gradual rollout. We'd like to know what it actually did on your machine.
Video: “Windows 11 KB5132061 is Now Auto-Enabling Memory Integrity!”, BrenTech YouTube channel, November 11, 2026 (5:09 PM Paris time), 2 min 29 s, independent creator: https://www.youtube.com/watch?v=kbl4qdqmErM
What Microsoft says: supported PCs “may now have memory integrity (HVCI) enabled during updates (…) while respecting existing user or IT administrator choices” (KB5127936 notes, included in KB5132061). If you had already turned it off, the rollout does not change it. Check it in Windows Security > Device security > Core isolation details.
Our questions:
- After the November update, is Memory integrity on? Was it on before, or did the update switch it on?
- Did you measure a difference in a game (same scene, on vs off)? Which game, CPU and GPU?
- Did a game, anti-cheat or tool (RGB, overclocking, monitoring) refuse to start, or did Windows list an incompatible driver?
- Did you keep it on, or turn it off? Why?
Please give your Windows version (25H2 or 26H2) and build number.
