Vulnerable Driver Blocklist

What is the Vulnerable Driver Blocklist?

The Microsoft Vulnerable Driver Blocklist is a Windows security feature that prevents drivers with known security vulnerabilities from loading.

While this improves system security, it can also block certain legitimate software that relies on vulnerable or unsigned drivers. If this feature is enabled, some products may fail to initialize or display driver-related errors.

Disable the Driver Blocklist

  1. Open Command Prompt as Administrator.
  2. Run the following command:

Copy

reg add "HKLM\SYSTEM\CurrentControlSet\Control\CI\Config" /v VulnerableDriverBlocklistEnable /t REG_DWORD /d 0 /f
  1. Restart your PC for the change to take effect.

Note

Disabling the Vulnerable Driver Blocklist reduces Windows security by allowing drivers that Microsoft would normally block. Only disable this feature if required for troubleshooting or if instructed by our documentation.
