    Device Security - Core Isolation


    Hi there,

    I'm trying to enable core isolation under the Device Security within Windows Defender but have come across an issue.

    I have an incompatible driver preventing the core isolation from enabling. The driver is named ftdibus.sys which is located in C:\Windows\System32\DriverStore\FileRepository\ftdibus.inf_amd64_5616cc9aa1fc2a73\amd64 on my laptop Dell Alienware 15 R2 win 10 Pro build 19042.

    Can anyone tell me if I need his driver? I've looked through the device manager Universal Serial Bus Controllers including hidden and it's not for any of them. I'm not able to delete it either as it states I need to be SYSTEM to do so.


    Thank you.

    :)

    core isolation disabled itself in bios on new computer

    Hello Khynnea,



    Thank you for writing to Microsoft Community Forums.



    It can be the BIOS update released by your manufacturer through windows updates which might have changed the status from Enabled to disabled. However here are the steps to enable it again.



    • Open start menu and search for Windows Defender Security Center.
    • Go to Device Security.
    • You will be able to find Core Isolation, please click on Core Isolation details.
    • Then you can turn it on.

    Restart is restart is required for the changes to be effective. Please write back, if you need any further assistance.

    Hope it helps.

    Device Security - Core Isolation

    Core Isolation

    In windows security under Core Isolation: Device security shows memory integrity can't be started. There may be an incompatibility on your device. I am also receiving message that controlled folder access blocked CNQMSWCS.l and C;/WINDOWS...' all in notifications.
    Any recommendations?
