Monitors your WordPress installation for core, plugin and theme updates and emails you when they are available. This plugin is ideal if you don’t login to your WordPress admin regularly or you support a client’s website.
Features
<ul>
<li>Set the interval of how often to check for updates; hourly, twice daily or daily.</li>
<li>Sets WordPress to check for updates more often meaning you get to know about updates sooner.</li>

This plugin is a fork of <a href="https://wordpress.org/extend/plugins/update-notifier/" rel="ugc">Update Notifier</a>. This plugin was forked because there seemed to be no further development on the existing plugin and there was no way to contact the original author to ask about taking ownership. WP Updates Notifier has the following improvements over Updates Notifier:
<ul>
<li>Completely rewritten from the ground up using best practises for writing WordPress plugins</li>
<li>Code wrapped in a class so better namespace.</li>
<li>You can set the cron interval, allowing for more frequent checks.</li>
<li>Update checks trigger WordPress internal update check before notification.</li>
<li>Allows you to set the ‘from address’.</li>
<li>Allows you to set multiple ‘to addresses’.</li>
<li>Makes use of the Settings API.</li>
<li>A number of available hooks and filters for advanced users.</li>
<li>Active support and development.</li>

WP Updates Notifier

It's ok for theme and plugins notifications, but notification about core updates does't work for more than one year!
This plugin probably won't recieve an update anymore.

Out-of date and not fully working

Sends email to notify you if there are any updates for your WordPress site. Can notify about core, plugin and theme updates.

This plugin will fix long filename problems on Windows systems when doing updates from third-party plugin repositories, such as updating from EDD based sites.
Usage Scenarios:
We’ve found that users on Windows systems that are upgrading themes and plugins from a third-party repository, such as an Easy Digital Downloads (EDD) site have problems. They will see an error message of “Update Failed: Could not create directory…”. The reason for this is that during the update process, the file name requested from the EDD site has the product name, user name and other information encoded within it so that EDD knows who is requesting the file. This results in a very long file name. This is not necessarily a problem WordPress itself, or even EDD, as this works on non-Windows systems. But if you are running WordPress on Windows and see this error, it is because of the long file name requested.
If you are using DesktopServer for your local development on Windows and would like to use the Windows Compatibility Fix plugin as a Design Time plugin, you can install this in your C:\xampplite\ds-plugings directory and it can then be automatically activated and used with all of your local development web sites. This allows you to use the plugin in your local environment, where it’s needed and not to deploy it to your live environment where it may not be needed. For more information on DesktopServer and local development tools, please visit our web site at: https://serverpress.com/get-desktopserver/
Because this fix is only needed on Windows systems, the plugin checks the operating system on which it is running and does not initialize itself. If you are having problems with the update process on non-Windows systems, it is more likely an issue with directory permissions.
How it Works:
The Windows Compatibility Fix plugin uses a couple of WordPress filters employed during the update process. It modifies the name of the file that is downloaded to your system, shortening it to just a few characters. This allows WordPress’s update process to work correctly on Windows systems by not creating the long file name in the first place.

Windows Compatibility Fix

I'm using DesktopServer on Windows and was unable to get a plugin update from an EDD store to update (not an EDD plugin). I came across a forum that mentioned this plugin, and figured I'd give it a try. After installing, the update worked perfectly.

Works Great!

Fixes long filename problem on Windows systems when doing updates, such as updating from EDD based sites.
