How to fix Ddkmd.sys blue screen error on Windows 10

4. Update drivers

If you know what part of the hardware is causing the problem, you can try to update the driver to the latest available version.

If the Ddkmd.sys error shows up while using a web browser like Chrome or Edge or while watching videos from YouTube or MediaPlayer; the faulty driver most probably is your display or video card driver.

The best solution to have all your drivers up to date automatically is to use DriverFix. 

5. Uninstall DuetDisplay / DisplayLink

DuetDisplay is a software application for macOS and Windows PC that allows the users to use their iPad as the secondary display.

While the software has been developed to increase productivity, some users have reported it to be conflicting with the core functions resulting in Ddkmd.sys error.

If you are using a secondary monitor with your computer, uninstalling any monitor software like the DuetDisplay and DisplayLink can fix the issue. You can uninstall the software from Control Panel.

Make sure you also delete any remaining drivers from the Temporary folder, Program Files, and Windows registry. Follow this article on how to clear leftover files after uninstalling software on Windows 10.

6. Disable / Uninstall Antivirus

If you have an antivirus program installed on your PC, it may be a good idea to disable it temporarily and check if that has any effect on the Ddkmd.sys error.

Antivirus software is known to create conflicts with system files and blocking legitimate connections due to security reasons.

However, if the security programs prevent a genuine program from functioning correctly, it can result in system errors. If you have recently installed an Antivirus program, disable it temporarily.

If the issue gets resolved, you may need to uninstall the antivirus and look for another program.  Preferably Malwarebytes, this program is light on your PC and does not create problems with system functions.
