Windows 11 Turns On Memory Integrity for More PCs - tech|
| (hx) 09:34 AM CET - Nov,11 2026 | The November 2026 Windows 11 update is enabling Memory Integrity on more eligible computers.
The change arrived first in October’s optional update and is included in the mandatory November Patch Tuesday release, KB5132061, for Windows 11 25H2 and 26H2.
Memory Integrity, also called HVCI, blocks untrusted kernel code and drivers. Microsoft says Windows checks hardware, drivers, and performance before turning it on, and it leaves the setting alone if a user or IT admin already disabled it.
In 2022 Microsoft published a support page that told gamers they could turn the feature off for better frame rates in some cases. That page has since been removed.
Tests have shown frame-rate drops of roughly 5 percent on newer CPUs and higher on older hardware, though results vary by game and system.
Users can check the status under Windows Security > Device security > Core isolation details and switch it off if needed. A restart is required for the change to take effect.
The feature remains optional for those who prefer maximum performance over the extra kernel protection. |
