How to Disable All Updates in WordPress

To hide all updates for WordPress Core, Plugins, and Themes, you can add specific code snippets to your functions.php file or create a simple plugin.

<?php 
add_filter( 'site_transient_update_plugins', '__return_empty_array' ); add_filter( 'transient_update_plugins', '__return_empty_array' ); add_filter( 'site_transient_update_themes', '__return_empty_array' ); add_filter( 'transient_update_themes', '__return_empty_array' ); // Disable core wp updates. add_filter( 'pre_site_transient_update_core', function ( $object = null ) { global $wp_version; // Return an empty object to prevent extra checks. return (object) array( 'last_checked' => time(),
		'updates'         => array(),
		'version_checked' => $wp_version,
	);
} );
add_action( 'init', function () {
	remove_action( 'init', 'wp_version_check' );
	add_filter( 'pre_option_update_core', '__return_null' );
	remove_all_filters( 'plugins_api' );
} );
// Disable even other external updates related to core.
