VxD

(Virtual Device Driver) A special type of Windows driver that allows Windows to perform functions that cannot be done by applications communicating with Windows in the normal manner. VxDs run at the most privileged CPU mode (ring 0) and allow low-level interaction with the hardware and internal Windows functions, such as memory management. For example, the operating system kernel is a VxD. See kernel.
