Hi Harry,
Thank you for your response.
I checked and configured as you explained, but the issue still exists.
Thank you,

Hello,
I need to disable the Memory integrity because it prevent for connect USB programmer FlashPro430.
Once I opened Core isolation application and switch Memory integrity to disable (Off), windows require to reboot the computer. After rebooting, the Memory integrity back to enable.
How can I resolve this and force the Memory integrity to stay in disable?
Thank you,
Alex Katsovich

On Windows 11, if incompatible drivers are detected, the system can silently re‑enable Memory Integrity to maintain protection. You should check
Device Manager > View > Show hidden devicesand look for drivers flagged as incompatible with HVCI; updating or replacing those drivers is the only supported way to keep the setting off.Also, please verify if your system is enrolled in Intune or another management solution, as those can push the “Core isolation” policy regardless of local configuration.

2026-02-24T08:15:18.7+00:00 Hi Alex,
On Windows 11, the “Memory integrity” setting is controlled by virtualization-based security and can be locked by Group Policy, registry, or driver compatibility checks. If you disable it in the Core Isolation UI but it re‑enables after reboot, that means a policy or enforcement mechanism is overriding your change. The first place to check is Group Policy under
Computer Configuration > Administrative Templates > System > Device Guard > Turn On Virtualization Based Security; if this is set to “Enabled,” it will force Memory integrity back on. You can also verify the registry key atHKLM\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegritya- value of1enforces it, while0disables it. If the setting is managed by your organization or Intune, you’ll need to adjust the policy there.Be aware that Microsoft strongly recommends keeping Memory integrity enabled, so the supported way to resolve driver issues is to update or replace the driver with one that is compatible. Forcing it off is possible only by changing the above policy or registry keys, but it reduces system protection.
Hope it helps!
Harry.
