1. Go to Default Domain Controller Security Settings> Software Restriction Policies> Trusted publishers
2. Change the settings from "Enterprise Administrators" to "End Users."
   
   • This sets AuthenticodeFlags = 0 under the following registry locations.
     
     • HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\SystemCertificates\TrustedPublisher\Safer\AuthenticodeFlags
