Clean the page head - WordPress

In Default, WordPress print too many unnecessary data in its page head. We can simply clean up the page head by using a simple code snippet.

//Clean WordPress head
add_action('after_setup_theme','start_cleanup');

function start_cleanup() {
  // Initialize the cleanup
  add_action('init', 'cleanup_head');
}

// WordPress cleanup function
function cleanup_head() {
  // EditURI link
  remove_action( 'wp_head', 'rsd_link' );
  // Category feed links
  remove_action( 'wp_head', 'feed_links_extra', 3 );
  // Post and comment feed links
  remove_action( 'wp_head', 'feed_links', 2 );
  // Windows Live Writer
  remove_action( 'wp_head', 'wlwmanifest_link' );
  // Index link
  remove_action( 'wp_head', 'index_rel_link' );
  // Previous link
  remove_action( 'wp_head', 'parent_post_rel_link', 10, 0 );
  // Start link
  remove_action( 'wp_head', 'start_post_rel_link', 10, 0 );
  // Shortlink
  remove_action( 'wp_head', 'wp_shortlink_wp_head', 10, 0 );
  // Links for adjacent posts
  remove_action( 'wp_head', 'adjacent_posts_rel_link_wp_head', 10, 0 );
  // WP version
  remove_action( 'wp_head', 'wp_generator' );
}
