    Is it possible the Yoga just has virtualization disabled in BIOS? That would stop memory integrity from working.

    If it was that simple, I think they would have stated that in the Lenovo Forum.

    But I'll go through the Bios to see if there is anything about virtualization that needs to be enabled.

    Task Manager shows Virtualization Disabled.

    I test that with my business laptop (I'm not at home now) running Windows 10.

    Disabling Virtualization from BIOS remove Memory Integrity option from Defender settings.

    I just went through the Bios and enabled Virtualization now I can get Core Isolation,

    but found 2 incompatible drivers that should be easy to fix. I only use external drive WD, I have to find the correct new drivers, I guess.

    Thanks,

    I had to uninstall the wdcsam64_prewin8.sys (2 occurrences) and now I can turn on memory integrity. 😊
