Routine Description:

    This function is called by the spooler everytime a new driver
    is copied to the system.  This function checks for appropriate
    registry keys in the registry.  If the new registry keys are not
    present, it will set the new keys with default values.  This function
    will handle the upgrading of information in the registry to the new driver format.

Arguments:

    dwLevel - version info for DRIVER_UPGRADE_INFO
    pDriverUpgradeInfo - pointer to DRIVER_UPGRADE_INFO_1

Return Value:

    TRUE for success and FALSE for failure
