Of note are website Content Management Systems (CMSs) such as Word Press, Joomla and Drupal simply because of their common use.
Not securing these by updating leaves your system open to compromise making your software vulnerable.
Better Functionality Updating your software will frequently provide feature and speed enhancements.
For example, recent updates to Word Press have been improved with the addition of contextual searches, user theme management, and even the ability to manage multiple sites from one control panel.
Instead, change preferences for how often you'd like to be notified of newer versions.
The default setting is to notify on a weekly basis.
For weekly updates, you can select the day of the week and the time of the day.
Squashing Bugs When you begin working on a brand new piece of software or are operating on the most updated CMS, you are at the highest functionality available.
Java Update is a feature that keeps your Windows computer up-to-date with the latest Java releases.
When you have auto update enabled, your system periodically checks for new versions of Java.
This is especially important when there is a new release available for software you use, because most change logs and update notes reveal previously-known exploits that have already been patched.
Public knowledge of these exploits leaves your application easy prey for malicious users who are out to exploit these now known issues.
