Under Microsoft Windows enhanced mode, a virtual device (VxD) can use the virtual keyboard device (VKD) and virtual display device (VDD) message mode services to provide user interaction. These services are especially useful to programs that implement security systems where the user is required to enter a password before any further operation can proceed.

The VKD and VDD message mode services are documented in the Microsoft Windows Device Driver Kit "Virtual Device Adaptation Guide."
