Memory Integrity (VBS)

On this page

Recommendation

Leave as default

Leave it enabled with compatible drivers.

If Windows reports an incompatible driver or measurements confirm a problem in a specific game, first update or replace the driver. Consider disabling the protection only as a last resort.

What changes

Section titled “What changes”

Memory Integrity, also known as HVCI, is a VBS feature: the hypervisor checks the code running in the Windows kernel and does not let unsigned or modified code through. This protects the kernel from malicious code injection even if an attacker gains administrator rights.

Exceptions and differences

Section titled “Exceptions and differences”

On Windows 11 the setting is hidden: there is no separate Memory Integrity card there, and the whole VBS package is managed by VBS (Memory Integrity, DeviceGuard, HVCI, CG). On Windows 10 BoosterX separated it from the general VBS setting because of anti-cheats.

App warning: BoosterX warns that FaceIt may require the feature to be enabled — according to the description shown, if after optimization the game on FaceIt “suddenly started running great”, the anti-cheat most likely required it to be enabled. Reverting the setting and rebooting is usually enough even with VBS disabled. If the anti-cheat keeps requiring it, enable the feature directly: above, enable Windows Security, then Settings → Update & Security → Windows Security → Open Windows Security → Device security → Core isolation details → Memory integrity.

If Windows considers a driver incompatible with memory integrity, Windows Security reports this and does not enable the protection until the driver is updated.

How to verify the result

Section titled “How to verify the result”

After reverting to the default state and rebooting, open Settings → Update & Security → Windows Security → Open Windows Security → Device security → Core isolation details: Memory integrity must be enabled. Incompatible drivers are displayed in the same section.

How to change and revert

Section titled “How to change and revert”

In BoosterX, open Optimization → Security → Hardening (VBS/UAC) → Memory Integrity (VBS) and move the toggle to the “Off” position: BoosterX will apply the default Windows state with memory integrity enabled. Click Apply at the bottom of the page; with Instant apply enabled, the change is applied immediately. To disable the protection, use the “On” position: BoosterX will disable memory integrity; to revert, set it back to “Off” and reboot. After the change, restart the computer — the core isolation state changes at boot.
