Can someone tell me where you are seeing these driver issues? I'm turning on Memory Integrity, rebooting and the warning to turn it on just pops back up again and it's off. No error message, nothing that seems pertinent in Event Viewer.

Confirm your results, this is the first build seeing this in Security. Worked automatically in my compliant devices, of course could not be activated in non-compliant legacy machines.
Have a great weekend fg.
Regards,
Thanks Johnny.

They must have checked previously, as I had to uninstall some programs and remove oem.inf files on some PC's and notebooks to enable it.
First checked in September and fixed early November
Hi Vienna,
They sure never checked on some of my machines that have incompatible drivers for memory integrity, the message just showed up with this Build, I've been running Win 11 Dev Builds from the beginning.
