The Enhanced Multimedia PS2 Keyboard driver is designed to support specific features of PS/2-based keyboards, particularly those with multimedia keys, special function keys, or advanced features (like volume control, play/pause, etc.). PS/2 keyboards use a legacy connection standard (round connector) rather than USB. This driver ensures that Windows properly recognizes and functions with the keyboard, enabling all its multimedia functions and special keys.
If you have an Enhanced Multimedia PS2 Keyboard, it is likely an older model or a keyboard that uses the PS/2 port on your computer. Modern systems may still have this connection, but USB keyboards are now far more common.
