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.

    A more simple way to solve this exact question:

    1. Right-click at Start button and select Device Manager
    2. At Device Manager Menu, Show Device by Driver
    3. Find manually your "old" drivers and, if it not have any devices attached, right-click at selected driver and "Remove driver".

    Simply removing old drivers is not always so easy. In my case, I traced the driver to a 10-year-old piece of photo editing software that I continue to use several times a month. That program - originally free - was subsumed into Adobe's outrageously-priced subscription-only graphics suite a few years back. I have been unable to find a suitable replacement, so I continue to live with the security exposure on both my desktop and laptop PC's. Life with computers is never simple!

    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.

    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!
