    Core Isolation preventing a driver from loading

    The driver "gdvr3.sys" was causing core isolation to turn off. After turning it back on and restarting, get the message that Core Isolation has blocked the driver from loading. However, it is not showing up under problems when I look under core isolation details. Not sure what next steps need to be.

    Core isolation not turning on

    I am running a AMD build with windows 10 and had my core isolation on prior. I downloaded an update on a driver for my Elgato game capture and now my Core isolation will not turn back on.

    Turn On or Off Core Isolation Memory Integrity in Windows 10  


    It looks like the .reg file in step 2 of Option Two in this tutorial worked to turn on Core isolation for you.

    Correct, you could use step 3 to turn it off.
