This tutorial will teach you how to update your WordPress installation.
Back up WordPress
Before you get started, it's a good idea to back up your website. This means if there are any issues you can easily restore your website. Complete instructions to make a backup can be found in the WordPress Backups section of the Codex.
Automatic Background Updates
For WordPress 3.7+, you don’t have to lift a finger to apply minor and security updates. Most sites are now able to automatically apply these updates in the background. If your site is capable of one-click updates without entering FTP credentials, then your site should be able to update from 3.7 to 3.7.1, 3.7.2, etc. (You’ll still need to click “Update Now” for major feature releases.)
You should be logged in to WordPress, and at your Dashboard. At the bottom of the center left section, it will tell you what version of WordPress you are currently using. Next to that will be a button to Update, if one is available. After you click this button, it will take you to a page called WordPress Updates.
There will be a button called Update Automatically. Click this button. The install process can take up to several minutes to complete. Once WordPress has been upgraded, information about the install will show up on the Update page. Now click the Go to Dashboard link.
On your Dashboard, you can now see the current version has changed.
