Driver Verifier is a tool included in Microsoft Windows that replaces the default operating system subroutines with ones that are specifically developed to catch device driver bugs. [1] Once enabled, it monitors and stresses drivers to detect illegal function calls or actions that may be causing system corruption.
Virtual device drivers represent a particular variant of device drivers. They are used to emulate a hardware device, particularly in virtualization environments, for example when a DOS program is run on a Microsoft Windows computer or when a guest operating system is run on, for example, a Xen host.

An INF file (setup Information file) is an INI plain-text file used by Microsoft Windows-based operating systems for the installation of software and drivers. [1] INF files are most commonly used for installing device drivers for hardware components. [2] Windows includes the IExpress tool for the creation of
In Windows XP, drivers account for 85% of the reported failures. In the Linux kernel 2.4.1 device driver code accounts for about 70% of the code size. [2] The driver fault can crash the whole system as it is running in the kernel mode. These findings resulted in various methodologies and techniques for verification of device drivers.
