Driver updates for Windows, along with many devices, such as network adapters, monitors, printers, and video cards, are automatically downloaded and installed through Windows Update. You probably already have the most recent drivers, but if you'd like to manually update or reinstall a driver, here's how:
There should be no driver differences between running on a macbook, a mac mini or a mac pro or even for running on a windows host running VMware Workstation (unless you're trying to run a macOS guest as that is prohibited on a windows host)
I have used Everest to determine that my network adapter is a RealTek RTL8139/810x Fast Ethernet Adapter and installed the appropriate driver. But I can't see any Local Area Connection in my Network Connections.
It should find a RedHat network adapter driver, follow the prompts and you're in business.
** I never bothered to locate the actual subfolder of the driver on the virtio-win-1-1 image, I just let windows do it for me. **
In order to improve network performance, special paravirtualized network drivers can be installed in Windows guests: to use them, you have to obtain those drivers and then install them on the VM guest os.
The Windows device manager should now detect a new network device. Just point the driver wizard to the CD-ROM containing the drivers. The drivers are not signed, choose install anyway and you are done.
