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.

    Hello Bob,

    I have the same issue with the 2 Samsung drivers as the original poster. I tried your suggestion of going into Safe Mode, found the drivers, but was still unable to delete them. The pop up said I required permission from the System to make changes to the file.

    I also tried Method 2 below and that didn't work either - the autorun didn't even locate the drivers.

    Any advice would be greatly appreciated!

    Linda

    I don't have any Samsung devices on my network, so this is especially frustrating.

    Hi,

    what about ftdibus.sys? I tried to find a solution for my issue but had no luck at all. Would this method work for ftdibus.sys as well?

    Hi Pete,

    It works for any driver. Just find the publisher name from the dism command, and then use PNPUtil.

    Hey Ive been trying to work this fix up myself however when I enable core isolation in defender I DO NOT get a list of driver issues and then on restart I am permanently stuck in a blue screen loop only fixed by restoring from a previous windows restore point.

    Does anyone have any thoughts if I cant see what drivers are causing the problem?

    Tried pretty much everything, memory check and scan, all windows updates done, all devise monitors are checked for drivers and are up to date.

    Really stuck on this now.

    Thanks.
