Disable all update notifications in WordPress

If you no longer wish to receive notifications of updates to your WordPress administration, a few lines of code in this tutorial will be sufficient to hide them. Updates of the core, themes and plugins will no longer appear!

Note: These tips only work for WordPress 3.0 onwards. We have not checked for WP 3.5 upwards.

Hide update notification from the core of WordPress

Log into your WordPress admin, then scroll down and click the Editor (under Appearance).

Then open the functions.php file from the list on the right.

In the end or beginning of file – including the theme TwentyTen, add the following lines of code:

add_filter ('pre_site_transient_update_core' create_function ('$ a', "return null;"));

Hide update notification of WordPress Themes

The procedure is identical. Reopen the functions.php file and paste these lines of code:

remove_action ('load-update-core.php', 'wp_update_themes');add_filter ('pre_site_transient_update_themes' create_function ('$ a', "return null;"));

Hide update notification of WordPress plugins

Again, just paste these lines in the functions.php file:

remove_action ('load-update-core.php', 'wp_update_plugins');add_filter ('pre_site_transient_update_plugins' create_function ('$ a', "return null;"));

Remember to Update the file.

WordPress is now configured to hide all notifications of updates.

Note : Please take backup of these files before any editing. We have not tested for current version of WP, From comments its verified they work fine up to 3.3.x. Your feedback is valuable.
