An Infrared Receiver Windows driver is a piece of software that allows your computer to communicate with an infrared (IR) receiver. The IR receiver is typically a hardware component that allows your computer to receive signals from infrared devices, such as remote controls, infrared keyboards, or other IR-based peripherals. The IR receiver itself is usually either integrated into your computer (e.g., in some laptops) or connected via a USB port (external IR receiver).

The driver allows Windows to recognize the IR hardware, interpret signals from the infrared devices, and process commands sent through infrared communication.
