Core isolation on Windows 11 not possible, in my case, because of these drivers

I tried to find them in Windows/Sys32/drivers (as suggested in other forums) and deleting them but with no success so how can I solve the problem allowing the activation of core isolation?

Core isolation not allowed for driver incompatibility

Hi,

Here is what typically works for most of the users who know the driver name as it is mentioned in Windows Security. Apparently, Microsoft changed/updated the incompatible driver list recently, which has ended up this issue for most of the users.

Method 1:

You can get the list of drivers by running this command in the elevated command prompt:

dism /online /get-drivers /format:table

After that, Make note of the Published Name (ex: "oem13.inf") of the driver that is shown as problematic.

Then use the pnputil command to delete the driver from the device:

pnputil /delete-driver <Published Name> /uninstall /force​

Please note that running this command would remove the device driver and the next time you use the device, it would not work. Reinstalling the driver might help.

Method 2:

Another alternative is using Autoruns to delete the driver. Download it from here:

https://live.sysinternals.com/autoruns.exe

Run it as administrator.

Go to the Driver tab, locate the driver and delete the same.

    Dear Fabrizio98it,

    Welcome to Microsoft Community.

    There is a Samsung's driver shown in the picture, may I ask whether you hava tried uninstalling the Samsung app?

    You can remove these incompatible drivers in safe mode.

    Press Win+I - Windows Update - Advanced Options - Recovery - Advanced Startup - Restart Now - Troubleshooting - Advanced Options - Startup Settings - Restart - Select 4 or F4 - Enter Safe Mode without Networking.(restart to exit Safe Mode)

    If there is anything not clear, please do not hesitate to let me know.

    Best regards,

    Method 2 worked for me. I had an incompatible driver left, zam64.sys, and this way I removed it, I was able to enable Core Isolation after computer restart.

    Thanks!

    First uninstall samsung related softwares completely and remove remaining sys file by booting windows into safe mode, then take ownership of that file and folder, then delete that particular file.
