How do I resolve this?

The driver has something to do with one of my older WD external hard drives.

Afaik you’ll need to either update or remove the driver or keep memory integrity off if the driver is needed but cannot be updated.

Sep 21, 2022 - A couple of weeks ago someone from WD called me and guided me to the process of removing anything related to WD from my computer and removed any WD software. Then after rebooting the computer, I downloaded the latest software update for the WD and then everything worked out well...

i have a M2 type WD580 blue. you will need to install the WD dashboard.
once installed you can update the firmware of the drive.
or, there is a registry entry you can add and alter to change HMB allocation size which is the problem that is causing the error.

Registry hack fixes WD SN770, SN580 Windows 11 24H2 blue screens (BSOD)

Certain WD SSD users are experiencing blue screens of death (BSODs) after updating to Windows 11 24H2. Thankfully, users have managed to figure out a Registry hack that fixes it.

Just uninstall the driver - you don't need it. That's what I did back in August 2022.

Bree said:
it is only ever needed if you want to use the WD encryption software that WD supply with their external usb drives.

The WD SES Device only shows in Device Manager while a WD usb drive is plugged in. To see (and be able to uninstall it along with its driver) at any other time you need to tell Device Manager to 'View > Show hidden devices'.

    UPDATE - 11 April 2026: due to lid hinges starting to break up this laptop has been retired from active duty. The OS with all software and files has been migrated to my System Seven in 'Other systems' to carry on as my general purpose 'main machine'.

    I've now clean installed 25H2 and used Garlin's scripts to update Secure Boot to CA 2023 and revoke the PCA 2011 certificates. It's new role is to test secure boot issues.

    Info for 2021-2026:
    fully 'Windows 11 ready' laptop. Windows 10 C: partition migrated from my old unsupported 'main machine' then upgraded to 11. A test migration ran Insider builds for 2 months. When 11 was released on 5th October 2021 it was re-imaged back to 10 and was offered the upgrade in Windows Update on 20th October. Windows Update offered the 22H2 Feature Update on 20th September 2022. It got the 23H2 Feature Update on 4th November 2023 through Windows Update, 24H2 on 3rd October 2024 through Windows Update by setting the Target Release Version for 24H2, and 25H2 on 30th September 2025 through Windows Update by setting the Target Release Version for 25H2.
