Signing Drivers with a Digital Certificate

Computer users without administrator privileges cannot install unsigned drivers! Drivers must be signed by certificates that Windows 7 trusts, while a user account with administrator privileges can install unsigned drivers. In the case of a network environment where ordinary users need to install unsigned drivers or applications, an administrator can authorize such installation using a self-signed digital certificate.

Digital Certificates allow users to identify that the source of the device driver or application is a legitimate publisher. It does not mean that the driver or application is bug free but its source is trustworthy that is, coming from its claimed source and it is intact.

A self-signed certificate will be valid only to your environment and can be created from a certificate authority server running Windows Server and Certificate Services.
