Configuring a Computer to Support Release-Signing
Before a release-signed driver package can be installed on a computer, follow these steps to configure the computer to support release signing:
Disable the TESTSIGNING Boot Configuration Option. For more information about this option, see the TESTSIGNING Boot Configuration Option.
Enable Code Integrity event logging and system auditing to help troubleshoot problems during release-signed driver installation and loading. For more information, see Enabling Code Integrity Event Logging and System Auditing.
After the computer is reconfigured to enable release-signing, restart the computer for the changes to take effect.
