The problem of program signature is actually that Microsoft has made a driver signature item in the operating system for its own protection measures. If it is a third-party driver, you will be prompted whether it is unsigned, otherwise the installation will not be allowed at all. Of course, some unsigned drivers will inevitably escape these tests and verifications and mix into Win 10 system. These softwares often need manual detection, so how to detect the unsigned driver of win 10? Please see the following, which is the driver detection method of win 10 without digital signature.
