Our task is to remove footer version that is displayed on the admin login as :

Step 1 : Go to : <Your project root directory>\wp-admin\includes\update.php > find a switch statement

switch ($cur->response)
{
	case 'development' :
		return sprintf ( __ ( 'You are using a development version (%1$s). 
				Cool! Please <a href="%2$s">stay updated</a>.' ), 
		get_bloginfo ( 'version', 'display' ), network_admin_url ( 'update-core.php' ) );
		break;
	
	case 'upgrade' :
		return sprintf ( '<strong>' . __ ( '<a href="%1$s">Get Version %2$s</a>' ) . '</strong>', 
		network_admin_url ( 'update-core.php' ), $cur->current );
		break;
	case 'latest' :
	default :
		return sprintf ( __ ( 'Version %s' ), 1.0 );
		break;
}

		get_bloginfo ( 'version', 'display' ), network_admin_url ( 'update-core.php' ) );
		break;
	
/*	case 'upgrade' :
