Issue: How to fix Microsoft Vulnerable Driver Blocklist grayed out in Windows?
Hello. I wanted to enable the Microsoft Vulnerable Driver Blocklist option in Windows but it is grayed out. Why is that and is there a way to fix this?
Solved Answer
The Microsoft Vulnerable Driver Blocklist is a critical security feature that prevents Windows from using drivers that have been identified as being vulnerable to security threats. It can help protect your system from malicious attacks and other security risks when enabled.
However, some users have reported that in Windows, the Microsoft Vulnerable Driver Blocklist option is grayed out. This means they are unable to enable this feature, leaving their systems vulnerable to security threats.
The problem could be caused by a number of factors, including out-of-date drivers,[1] missing updates, or compatibility issues with specific hardware or software configurations. If unresolved, it can expose users to potential security risks such as malware infections or unauthorized system access.
Users can address this issue by updating their drivers, installing the latest Windows updates, or disabling certain third-party software that may be causing conflicts with the feature. It's also a good idea to run a full system scan with a trustworthy antivirus program to detect and remove any potential threats.
