    RTKVHD64.sys Driver Error - Memory integrity & Core isolation


    Hi there. I've recently updated my computer from Windows 10 to Windows 11. Like with many people who have done the same, I'm getting an error when attempting to fix the "Core isolation" errors in the Device Security / Windows Security Dashboard. Specifically, I'm having an issue with enabling Memory integrity, due to having some incompatible drivers. They appear to be Realtek High Definition Audio drivers.Text: RTKVHD64.sysRealtek Semiconductor Corp.Device: Realtek High Definition AudioImport date: 6/13/2023Driver date: 3/28/2013Driver version: 6.0.1.6873Published name: oem59.infRTKVHD64.sysRe

    Core Isolation Memory Integrity fails to enable because of incompatible driver wdcsam64_prewin8.sys

    Hi Lawrence I'm Greg, 10 years awarded Windows MVP, here to help you.

    You can remove the unneeded driver as shown in first link or wait for the replacement WD is promising in the second link:

    Here is more information about Memory Integrity to further understand it:

    There are a rising number of cases of Memory Integrity recently, which according to a senior MVP and Moderator here is due to another attempt by Microsoft to certify manufacturer's drivers - something which has been tried and failed before due to some manufacturers ignoring it. It also appears to be buggy because its flagging Windows System drivers. Here is what you can do:

    1) Make sure Secure Boot and TPM are enabled to get the full stable Security benefits of Windows 11:

    RTKVHD64.sys Driver Error - Memory integrity & Core isolation

    core isolation not supported

    The igdkmd64.sys is the Intel HD graphics driver for your 1st gen i3 M380. I have the same with my i5 M520.

    This processor generation is long out of support and Intel have stopped developing the drivers for them. There are no new drivers compatible with Memory Integrity.

    The only way to turn on Core Isolation would be to uninstall the Intel graphics drivers and use the Microsoft Basic Display Adapter instead. That's not really a practical solution so you (and I) must accept that we cannot use Core Isolation. This is not as bad as it sounds, the benefit of Memory Integrity is that it prevents malware sneaking in as a driver update. But it shouldn't be able to get that far if your AV protection is doing its job. More here from the How-To Geek:
