How to Disable Windows Defender Credential Guard

As an expert in tech-related issues and troubleshooting tech problems, I, Tracy, want to guide you through the steps to disable Windows Defender Credential Guard. This security feature, designed to protect your system against advanced threats that can potentially compromise your credentials, sometimes needs to be turned off for troubleshooting or compatibility reasons. Let’s get straight to the point without any fluff.

Understanding Windows Defender Credential Guard

Before we dive into the disabling process, it’s important to understand what Windows Defender Credential Guard does. It uses virtualization-based security to isolate secrets so that only privileged system software can access them. This is typically useful in enterprise environments where security is paramount.

Prerequisites to Consider

Disabling Windows Defender Credential Guard should not be taken lightly and should only be done if necessary. Make sure you’ve backed up important data, as changing system settings can sometimes lead to unforeseen consequences.

Steps to Disable Windows Defender Credential Guard

  1. Navigate to the Group Policy Editor by typing gpedit.msc in the Run dialog (accessed by pressing Win + R).
  2. Go to Computer Configuration > Administrative Templates > System > Device Guard.
  3. Find and double-click on Turn On Virtualization Based Security.
  4. Set the policy to Disabled, then click Apply and OK.
  5. Restart your computer to apply the changes.

Alternatively, Credential Guard can also be disabled via the Registry Editor or by using the bcdedit command. Please note that these methods require a level of expertise and are only recommended for advanced users.

Verifying that Credential Guard is Disabled

After your system restarts, it’s essential to make sure that Windows Defender Credential Guard is indeed disabled.

  1. Open the Task Manager and go to the Performance tab.
  2. Look for the Virtualization section. If Credential Guard is disabled, it should read “Not enabled” under Virtualization Based Security.
