I can't turn on memory integrity in Windows 11 even though no incompatible drivers are listed.

Hi everyone,

Thought I'd share this for our information.

Yesterday, my Windows Security icon showed action necessary. Opened Security and it advised I turn Memory Integrity on. Tried to turn it on - would not work. Got the message as you have done - can't turn on due to incompatible drivers. Ran the scan and no incompatible drivers were listed. I fiddled about uninstalling apps/etc as some of you have done to no avail. Then I checked my history of Windows updates and discovered that the following had been installed the day before:

Update for Microsoft Windows (KB5034467)

Feature Update for Windows 11 23H2 via Enablement Package (KB5027397)

Security Update for Microsoft Windows (KB5035853)

I deleted all three one after the other and then rebooted. After rebooting, the tray icon showed no action necessary. Opened it anyway and clicked Device Security - Core isolation - Core isolation details and Memory Integrity was on - but it also popped up a message saying I had to reboot for changes to take effect. Rebooted and all is fine.

Tried this but it did not work.

Uninstalled updates mentioned but problem persists.

I have the same case.

Running a Dell Vostro 3500 i5 11th Gen Win 11 22H2.

No incompatible drivers are listed, even ran autoruns, no incompatible drivers found.

Yet still can't turn memory integrity on.

this is my system summary
