SetupDiSelectBestCompatDrv function

The SetupDiSelectBestCompatDrv function is the default handler for the DIF_SELECTBESTCOMPATDRV installation request.


WINSETUPAPI BOOL SetupDiSelectBestCompatDrv(
  HDEVINFO         DeviceInfoSet,



A handle to a device information set that contains a device information element that represents the device for which to select the best compatible driver.


A pointer to an SP_DEVINFO_DATA structure that specifies the device information element in DeviceInfoSet. SetupDiSelectBestCompatDrv selects the best driver for a device information element from the compatible driver list for the specified device.

Return Value

If the operation succeeds, SetupDiSelectBestCompatDrv returns TRUE. Otherwise, the function returns FALSE and the logged error can be retrieved by a call to GetLastError.


If the caller of SetupDiSelectBestCompatDrv is a member of the Administrators group and the class of the device is different that the class of the selected driver, SetupDiSelectBestCompatDrv sets the class of the device to the class of the driver. If this behavior is not desired, call this function at a lower privilege level.

Note  Only a class installer should call SetupDiSelectBestCompatDrv and only in those situations where the class installer must perform driver selection operations after SetupDiSelectBestCompatDrv completes the default driver selection operation. In such situations, the class installer must directly call SetupDiSelectBestCompatDrv when the installer processes a DIF_SELECTBESTCOMPATDRV request. For more information about calling the default handler, see Calling Default DIF Code Handlers.
SetupDiSelectBestCompatDrv is primarily designed to select the best compatible driver for a device information element on a local computer. Although SetupDiSelectBestCompatDrv will not fail if the device information set is for a remote computer, the result is of limited use because the device information set cannot subsequently be used as input with DIF_Xxx installation requests or SetupDiXxx functions that do not support operations for a remote computer. In particular, the device information set cannot subsequently be used as input with a DIF_INSTALLDEVICE installation request to install a device on a remote computer.

For information about how the best driver is selected, see How Windows Selects Drivers.

To get the selected driver for a device, call SetupDiGetSelectedDriver.
