This article describes steps to enable or disable Microsoft Vulnerable Driver Blocklist in Windows 11.

Starting with Windows 11, the Microsoft Vulnerable Driver Blocklist feature is enabled by default. However, you can turn it on and off using the Windows Security app.

The blocklist is enabled on systems that have memory security (aka Hypervisor-protected Code Integrity (HVCI)) enabled or run Windows in S Mode.

With the feature, Windows will automatically block drivers that cause Windows devices to malfunction or become unstable. However, this feature may also interfere with the valid device’s driver, making the device not function properly.

When you enable Microsoft Vulnerable Devier Blocklist, you should monitor your device performance so that working devices are not mistakenly blocked.
