This security setting determines what happens when an attempt is made to install a device driver (by means of Setup API) that has not been tested by the Windows Hardware Quality Lab (WHQL).

The options are:

• Silently succeed
  
  
• Warn but allow installation
  
  
• Do not allow installation
  
  

Default: Warn but allow installation.

You can configure this security setting by opening the appropriate policy and expanding the console tree as such: Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\

For specific instructions about how to configure security policy settings, see Edit security settings on a Group Policy object.
