How to control initial wp_head() output?

Here is the current list of actions that is currently hooked by default to wp_head

Reposted here to avoid unnecessary opening multiple browser windows

add_action( 'wp_head',             '_wp_render_title_tag',            1     );
add_action( 'wp_head',             'wp_enqueue_scripts',              1     );
add_action( 'wp_head',             'feed_links',                      2     );
add_action( 'wp_head',             'feed_links_extra',                3     );
add_action( 'wp_head',             'rsd_link'                               );
add_action( 'wp_head',             'wlwmanifest_link'                       );
add_action( 'wp_head',             'adjacent_posts_rel_link_wp_head', 10, 0 );
add_action( 'wp_head',             'locale_stylesheet'                      );
add_action( 'wp_head',             'noindex',                          1    );
add_action( 'wp_head',             'print_emoji_detection_script',     7    );
add_action( 'wp_head',             'wp_print_styles',                  8    );
add_action( 'wp_head',             'wp_print_head_scripts',            9    );
add_action( 'wp_head',             'wp_generator'                           );
add_action( 'wp_head',             'rel_canonical'                          );
add_action( 'wp_head',             'wp_shortlink_wp_head',            10, 0 );
add_action( 'wp_head',             'wp_site_icon',                    99    );

if ( isset( $_GET['replytocom'] ) )
    add_action( 'wp_head', 'wp_no_robots' );

You can remove any action with remove_action()

remove_action( 'wp_head', 'wp_print_styles, 8 );

Just remember, an action need to be removed with the same priority it was added.

EDIT

An important note here. The foillowing actions should not be removed as this causes serious issues with how stylesheets and scripts are loaded

• locate_stylesheet

• wp_print_styles

• wp_generator

• wp_enqueue_scripts

If you need something specific removed, rather remove the call back function with remove_action or use the specific functions allocated to remove styles and scripts
