What is the PCI Express Root Port Windows Driver?
The PCI Express Root Port is a component of the PCI Express (PCIe) architecture on a computer's motherboard, and it is responsible for managing communication between the system's processor (CPU) and the various PCIe devices, such as graphics cards, network cards, storage controllers, and other expansion cards.
In Windows, the PCI Express Root Port driver is a device driver that enables the operating system to interact with the PCIe root port hardware. This driver is part of the chipset drivers and is essential for the operating system to recognize and properly communicate with devices connected via PCIe slots.
The PCI Express Root Port may appear in the Device Manager under the category "System devices." It could be listed as "PCI Express Root Port" or something similar, depending on the system's chipset.
