SIGVERIF
There is only one tool I could find that is used to verify digital signatures for system files and device drivers, it is called the signature verification tool otherwise known as Sigverif.exe.
1. Only administrators can install a hardware device if any type of user input is required. Any user can install a hardware device only if the following are true: the device drivers can be installed without user input, all files necessary for a complete installation are present, the drivers have been digitally signed ( digitally signatures are digital codes that can be used to authenticate the sources of files), and there are no errors during installation. If one of these conditions is not met, someone logged onto the system with administrative privileges must do the installation.

I don't know what it means
When the computer and system detects a new device attached, an inquiry signal is sent to device requesting ID information. The Plug and Play compatible device responds with its identification code. The system searches for an ID in its device tables that matches the response. if a match is found it loads drivers for that device, tries to perform automatic configuration for the device and make it available for the software applications. If there is no matching device available, depending on the system and version in use, it may display available drivers and ask which to use or it may ask to search the internet or a manufacturers site for drivers or it may ask for the location of drivers on the system or it may declare the device not available.
A computer is made up of many technical systems. The registry is a special database that holds key information about your system, including the device drivers.
