Based on the hardware ID provided ( VEN_8086&DEV_8C22 ), this device is the . This hardware is natively supported by modern Windows versions (8, 10, 11), but often requires a manual feature override in the driver configuration files to ensure the correct drivers install or to resolve compatibility warnings during OS deployment.
If you are still experiencing issues, it is recommended to search specifically for "Intel Chipset Device Software 10.1.1.44" or later, which often includes patches for the 8 Series/C220 series controllers.
