6. Toggle the switch under Memory integrity to turn it Off.

7. Restart your PC to apply the changes.

How to Disable Device Guard and Credential Guard

Device Guard and Credential Guard don’t play well with other virtualization software, including VMware Workstation. You may encounter an error saying Device Guard/Credential Guard is enabled when trying to power on the VMware Workstation.

Since you intend to use third-party virtualization software, you can safely disable Device Guard and Credential Guard using the Registry Editor.

That said, modifying the Windows Registry involves risk. We recommend you create a restore point and take a registry backup before attempting any modifications.

To disable Device Guard and Credential Guard:

1. Press Win + R to open Run.

2. Type regedit and click OK to open Registry Editor.

3. In Registry Editor, navigate to the following location:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

4. In the right pane, locate the LsaCfgFlags DWORD value. You’ll need to create a new key if no such value exists.
   

5. To create a new key, right-click the Lsa subkey in the left pane and select New < DWORD (32-bit) value. Rename the value as LsaCfgFlags.

6. Next, double-click on LsaCfgFlags and type 0 in the Value data field.
   

7. Click OK to save the changes.

8. Next, in Registry Editor, navigate to the following location:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard

9. In the right pane, check if the EnableVirtualizationBasedSecurity value exists. If not, right-click the DeviceGuard subkey and select New > DWORD (32-bit) Value.
   

10. Next, rename the key as EnableVirtualizationBasedSecurity and set its value to 0.
    

11. Click OK to save the changes.

Restart your computer to apply the changes and disable Device Guard and Credential Guard. If you ever need to enable these features, modify the value data and change it to 1.
