Windows Device Manager contains a list of all hardware components on the computer and the components' associated drivers. To reinstall the Microsoft Virtual Wi-Fi Miniport adaptor, you must remove the device from Device Manager. You then refresh the window, and Device Manager automatically reinstalls the software. You can also upgrade a driver in the Device Manager utility.
Click the Windows "Start" button and type "device manager" in the search text box. Press "Enter" to open the utility.
Click the arrow next to "Network Adapters." A list of Wi-Fi and local adaptors is shown. Right-click the "Microsoft Virtual Wi-Fi Miniport Adapter" icon and select "Uninstall."
Click the "Action" menu item after the driver uninstalls. Click "Scan for Hardware Changes." The window refreshes and the Wi-Fi adaptor is reinstalled.
Right-click the "Microsoft Virtual Wi-Fi Miniport Adapter" icon again. Click "Properties." Click the "Driver" tab. Click "Update" to upgrade the driver version. Upgrading the driver software fixes bugs and updates the version to the latest Microsoft-approved driver version.
