Whenever WordPress performs a core update, it automatically pulls down the following files onto the root:
<ul>
<li><code>license.txt</code></li>
<li><code>readme.html</code></li>
<li><code>wp-config-sample.php</code></li>
</ul>
These files aren’t an inherent security risk by themselves; however they are uneccessary clutter on the root of your site (why would you want a <code>wp-config-sample.php</code> file on your production website?!); and it’s just another easy-to-read vector confirming that you have a WordPress site for script-kiddies to scrape and attack.
Simply install this plugin and it will clean up those files every time you perform a core WordPress update.

Core Files Update Cleanup

This plugin deletes the unnecessary license.txt, readme.html and wp-config-sample.php files after a core update.

With every major WordPress Core Update, WordPress.org will be pushing out new versions of it’s own plugins and themes. What this plugin does is block that new content from downloaden onto your webserver.
There are a few good reasons you want this: 
* Avoid backups being unneededly big in size 
* Avoid longer backup creation and restore times 
* Lower the risk of getting hacked due to heaps of unused PHP code on your webserver
This is an UltraFast plugin. This means it will not use the database connection, it will not create a settings screen etc. Effectively it is only a single line of code we are adding to WordPress.
