unsupportable drivers

Question

How do I find the unsupportable drivers on my computer? These drivers are preventing me from turning on memory integrity.

Answer 1

Hello,

Please try the following steps:

1. Open Windows Security → Device security → Core isolation details.
2. Click Review incompatible drivers to check which drivers are causing the issue.

Contact the manufacturer of the affected device to see whether an updated driver is available.

Alternatively, note the published name shown under “Review incompatible drivers.”

For example, suppose it shows oem456.inf.

Open an elevated Command Prompt (Run as administrator).

Enter the following command and press Enter to delete the driver:

pnputil.exe /d oem456.inf

Open Core isolation again and turn Memory integrity On.

If you cannot turn it on, click Scan again to recheck for incompatible drivers.

If any incompatible drivers are found, delete them using the same Command Prompt method.

Answer 2

On Windows 11, drivers that are “unsupportable” for Memory integrity are the ones that Windows Security reports as blocking the feature. Windows does not provide a separate automatic list outside of this interface.

To find them:

1. Open the Core isolation page
   • Select Start > Settings > Privacy & security > Windows Security > Device security.
   • Under Core isolation, select Core isolation details.
2. Check Memory integrity status
   • If Memory integrity is Off and blocked by drivers, Windows Security shows a message that one or more drivers are incompatible.
   • In that same view, the blocking drivers are listed by driver name and company name. This list is effectively the “unsupportable” drivers for Memory integrity on that device.
3. Address the listed drivers
   • First, check Windows Update for newer, compatible versions of those drivers.
   • If none are available, go to the hardware or software manufacturer’s website and look for updated drivers that support Memory integrity / HVCI.
   • If updated drivers are not available, the only way to enable Memory integrity may be to remove or replace the associated hardware/software that uses those drivers.

If a driver is already being blocked from loading because of Memory integrity, Windows will show a notification like “A driver can’t load on this device,” which also includes the driver name and company. That notification and the Core isolation details page together provide the complete list of drivers that are not compatible with Memory integrity on the system.
