    How to Turn On or Off Core Isolation Memory Integrity in Windows 10


    The Windows 10 Creators Update introduced a new experience called the Windows Defender Security Center to make it is easier for you to view and control the security protections you choose and better understand the security features already protecting you on your Windows 10 device.

    Starting with Windows 10 build 17093, the Device security page was added to Windows Security that provides you with status reporting and management of security features built into your devices including toggling features on to provide enhanced protections.

    One Device security is Core isolation that provides virtualization-based security features to protect core parts of your device.

    Memory integrity is a security feature of Core isolation that prevents attacks from inserting malicious code into high-security processes.

    See also:
    It is required to have Virtualization enabled for your CPU in your UEFI firmware settings to have Core isolation Memory integrity available.

    Turn On or Off Core Isolation Memory Integrity in Windows 10

    Hello Ita1, *Smile

    I'm not sure either, but this setting has always been turned off by default for me so far.

    this setting = VBS, right?

    What's the meaning than of "for older systems, customers will have the ability to opt in post upgrade using [...]"?

    Older system=upgrade?

    Yes, core isolation is VBS.

    The line below means that they will be able to set it like in the tutorial.

    txs for your kind reply Brink!
    right
    yes but for devices that meet the minimum requirements otherwise the reliance on hardware would be useless.
    So, i think that older system should be explained as "system that come from an older branch" (eg 10 FCU) otherwise it doesn't make sense...

    From the article you linked Shawn:
    My Logitech webcam is one of those drivers that doesn't work now, with this turned on.

    But, Microsoft provides their own generic drivers for webcams(in Device Manager), just basic ones with no frills, but enough to work in Skype.

    Samsung and Logitech are notorious for not updating their certificates, so it is to be expected I guess*sarc

    Your welcome Shawn.
    I have upgraded my main system to the RP(yeah I couldn't wait*Redface) and now have the option, and turned it on.
    If the generic driver hadn't worked, I would have turned it off, but I don't need any of the extra features anyhow.
    By the way, one will need to do the same for the web cams mic also.

    Hmm, this below is what I'm seeing in Windows 10 build 17639.

    I'm unable to turn off "Memory integrity", but I do not have any group policies configured despite the red message below. *Confused

    If you feel like experimenting, I found this:

    set to 0
    Code: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity[/quote]

    Thank you Cliff. I added that as Option Two.

    I'm surprised the registry key is not hash protected though.
