    Hi Pauli,

    And it is clearly happy on a new machine. 👍

    Never complained before on previous Dev Builds on machines with memory Integrity off. Just this Build 22523.

    They are checking things closer.

    Hi @fg2001,

    I just turned on Core Isolation\Memory Integrity and restarted. It remained on. This is an Hyper-V VM installation ( 2nd-gen ).

    If I try to turn on Core Isolation\Memory integrity in an MBR installation, it cannot be turned on. I receive a message box reading "There is drivers incompatibility and I should rectify it before I try to turn the feature on." or something to that effect.

    Apparently, they just started checking for the memory Integrity feature on this Build 22523, they did not check in previous builds.

    Looks like with Hyper-V they can emulate anything, but I wonder how much of a validation test is running in VM instead of a real machine? 😎
