Installing an Inbox Driver or a Preinstalled Driver
If there is an inbox driver or a preinstalled driver that matches a device, Windows automatically installs the driver that has the best match to the device. Windows will not prompt the user to insert a distribution medium. In addition, Windows does not attempt to access Windows Update to determine whether there is a Windows Update driver that is a better match than the drivers that are already installed on the computer.
For information about how Windows selects the driver that has the best match to a device, see How Windows Selects Drivers.
