If you need to keep driver signature enforcement off permanently (e.g., for continuous testing or legacy equipment),
you can use Command Prompt.Press the Windows Key, type cmd in the search box, and select Run as administrator.
Run the following two commands, pressing Enter after each:
bcdedit /set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit /set testsigning ON
Restart your computer.
To re-enable it later, open an administrator Command Prompt and run
bcdedit /set testsigning OFF and
bcdedit /deletevalue
Restart your computer.
