Driver Verifier
Driver Verifier ( Verifier . exe ) was first introduced as a "command-line" utility in Windows 2000; in Windows XP , it gained an easy-to-use graphical user interface , called "Driver Verifier Manager" , that makes it possible to enable a standard or custom set of settings to select which drivers to test and verify .
