The Windows Virtual Wi-Fi Miniport adapter creates a virtual duplicate of the wireless network adapter installed to the computer. The Virtual Wi-Fi Miniport adapter is enabled automatically when a wireless network card is added to Windows 7, but users can uninstall and remove the adapter from the computer at any time. If your computer comes with Windows 7 and a wireless network adapter, but you can't find the Virtual Wi-Fi Miniport adapter in Device Manager, you can reinstall the device software from the command line.
