The OEM Capture Windows driver refers to a driver used by a capture device (such as a video capture card, camera, or other hardware used to capture video or images) that is made by an Original Equipment Manufacturer (OEM). The term "OEM" simply refers to the manufacturer that produces the hardware, which is often branded under a different name. In the context of the OEM Capture driver, it typically refers to the drivers provided for video capture devices that are used to capture, record, or stream video from sources like cameras, gaming consoles, or analog video signals.

These capture devices can be used for a variety of purposes, such as:

• Video capture: Capturing video from external sources like VCRs, camcorders, game consoles, or security cameras.
• Screen capture: Capturing your computer screen or window for video recording or streaming.
• Streaming: Capturing video input for live streaming purposes.

The OEM Capture driver allows Windows to communicate with and utilize these capture devices, enabling you to view, record, or stream video from the connected source.
