When WordPress is updated, it re-installs wp-config-sample.php, readme files, and license files even though you may have deleted them before. This plugin automatically removes these files when WordPress is manually or automatically updated. It also removes these files when activating the plugin for the first time. Removing these files is not mandatory, but you may want to if you don’t want them to expose your WordPress version or if you just like to keep things neat and clean.
Files that are removed:
<ul>
<li>License files, both default and localized</li>
<li>Readme files, both default and localized</li>
<li>wp-config-sample.php</li>
<li>wp-admin/install.php</li>
</ul>
You may not want to install this plugin if you’re using a plugin or service to scans your site to verify checksums on the core files. When the removed files are missing it might result in warnings.
<h3>Manual installation</h3>
<ol>
<li>Upload the <code>wp-core-update-cleaner</code> directory to the <code>/wp-content/plugins/</code> directory.</li>
<li>Activate the plugin through the ‘Plugins’ menu in WordPress.</li>
</ol>

This plugin removes the WordPress update nag that appears at the top of all admin pages when a new version of WordPress is released.
Tired of WordPress nagging you about a new release? Maybe you already know about it and want to hold off on an update and would rather not see the update nag on every admin page you visit. Activate this plugin and be bothered no more!
The status of your version of WordPress (be it current or out-of-date) is still reflected in the footer of your admin pages and in the update count link in the admin bar.
And certainly, of course, I don’t advocate completely ignoring the fact that updates often contain fixes for critical bugs or exploits. However, there are various other means of learning about updates; and once known, not everyone is able or willing to update immediately.
