Windows 11 will not show incompatible drivers

In new windows 11 up to date as of writing this. Core isolation memory integrity does not work and will not turn on. Every time I scan for incompatible drivers, none are listed. Checked the windows update, the system is up to date, and no errors in device drivers were found. All drivers appear up to date. BIOS most recent available (the same driver that was installed prior to this error occurring. None of the threads seem to address this, only ones where the driver is known. The DG readiness tool is not user-friendly for everyday users. Need a solution that can be done at home without having to be an IT guru or MSCE certified. It will not let me upload the screenshot or picture, keep getting errors in that as well.

    Here is something I discovered. I to have incomparable driver and it DID show the driver being (DellD3.WinSVC.DLauncher) I went looking for this driver it but it was not present. I then went back and tried again and the incomparable driver was not shown vanished just like that. I have been able to find out nil information anywhere on the driver shown above and my core isolation remains off.

    I guess I should have been more specific - the Memory integrity slider is greyed out AND indicates that Memory integrity is off, so the problem is still not resolved.

    The registry edit did not work for me. I set "REG_DWORD" of "Enabled" in "HyperVisorEnforcedCodeIntegrity" to 1 and then rebooted. Now when I try to enable Memory integrity Windows is telling me that setting is controlled by the System Administrator and the slider for "On/Off" is greyed out. I verified that I am the System Administrator so unclear why it won't let me enable Memory integrity.

    Even if the slider is greyed out it will show if it's enabled or not, and you can use the tool I mentioned to see the state: Device Guard and Credential Guard hardware readiness tool, that I found looking for a tool that could detect incompatible drivers, but it found nothing too. But at least it shows for me that the feature is working... It really is not optimal to have something locked... but, this is better than nothing... It being greyed out doesn't mean it don't work, and with DG readiness tool you can confirm it...

    I used an windows 10 tool (Device Guard and Credential Guard hardware readiness tool) that could teorically find any incompatible driver, and it found nothing at all, The tool is here: https://www.microsoft.com/en-us/download/details.aspx?id=53337 

    all you need is to unzip it to an folder, open powershell with admin and just use these commands:

    Set-ExecutionPolicy Unrestricted

    Then on the folder that you unziped the tool:

    .\DG_Readiness_Tool_v3.6.ps1 -capable

    So... As I had found nothing I gave up... and used the regedit method, just adding an dword Enabled with 1 as the value in HKLM\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity

    Same as:

    reg add "HKLM\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity" /v "Enabled" /t REG_DWORD /d 1 /f

    Or a .reg with

    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity]

    "Enabled"=dword:00000001

    I've confirmed most info here:

    https://learn.microsoft.com/en-us/windows/security/hardware-security/enable-virtualization-based-protection-of-code-integrity#troubleshooting 

    This method that was mentioned earlier works fine... Memory Integrity works with no issues.

    Just couldn't leave enabled the Kernel-mode Hardware-enforced Stack Protection as it would crash some software I have as if there's low memory... But had to force this one through regedit too...

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\KernelShadowStacks add the dword Enabled and set value to 1...

    or:
    reg add "HKLM\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\KernelShadowStacks /v "Enabled" /t REG_DWORD /d 1 /f

    You can create an .reg file with:

    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\KernelShadowStacks]

    "Enabled"=dword:00000001

    I would recommend to just use those methods that was suggested by others before, as however the problem with the not listed incompatible drivers is, it's time consuming to discover what causes it, would be glad if someone could come up with another tool as the Device Guard and Credential Guard hardware readiness tool but that could find the incompatible drivers... All I've got with that is that my OS is not recognised, as this tool is for Windows 10 and Server...
