The GKX Ethernet Adapter is likely a network interface card (NIC) or a USB-to-Ethernet adapter manufactured by a company or brand called GKX. These adapters are commonly used to provide Ethernet connectivity to computers or devices that do not have a built-in Ethernet port or to add additional Ethernet ports to a system.

To use the adapter on a Windows machine, you need to install the appropriate driver for it. The driver enables Windows to recognize and work with the adapter, allowing it to function properly for wired network connections.
