This plugin disables the WordPress update notifications, as well as update notifications of different plugins. It is ideal to deliver a complete WordPress and not bother the user with alerts. Silence!
<h4>Please note!</h4>
It’s very important that you keep your WordPress plugins up to date. If you don’t, your blog or website could be susceptible to security vulnerabilities or performance issues. If you use this plugin, you must make sure you keep yourself up to date with new releases of your active plugins and update them as new versions are released.

Major features :
<ul>
<li>Disable plugins updates.</li>
<li>Disable themes updates.</li>
<li>Disable translation updates.</li>
<li>Disable WordPress core updates.</li>
</ul>
PS: Used there features if you know what you are doing. No updates = Security holes, but sometimes updates may break your website. 
WordPress has added a quite convenient feature since version 3.7: Automatic update.
But sometimes, updates can be a real problem for your website. 
It is important to make updates to avoid security problems, but you must be very careful when applying updates. 
For example, if you use a prenium theme and you have not made a child theme for the changes. If the theme requires an update, it may delete all your changes and lost working hours….
But be careful, it’s to be used, if you know what you’re doing. You have to be on the lookout for changes made to the plugins. 
If a correction has been made to fill a security hole or just to improve the plugin.

WP Disables Updates

A simple and effective plugin to turn off WordPress update notifications selectively. I have found two uses for this so far:

1. When a premium theme is broken and is erroneously reporting that there is an update available and there is not.
2. When you want to disable certain update notifications on a production site because you prefer to test them locally, commit them to your repository and push the changes to production.

Simple and Works

WP Disables Updates allow you to disables plugin or themes or wordpress core updates.
