Activation and deactivation of Windows Test mode

Windows test mode allows you to run programs and drivers that are normally blocked for security reasons. As an option for advanced users, enabling it can allow untrusted software to run, even without a digital signature. However, this can present risks such as potential malware. It is therefore recommended to use it temporarily and to take precautions when downloading from the Web during this period. Have you ever had the chance to use this feature or do you know other tips for testing unsigned programs?
