Why Do I Need Java Updates?
Java is technology that allows you to create documents, play games, experience advanced website features and do other fun and useful things using desktop and Web-based software applications. Java Update automatically checks for updates, and alerts you when a newer version of Java is available. Java updates are critical to ensuring you can continue using your favorite applications safely and effectively.

Purpose
-
"Java Update" installs the most current version of Java on your computer. The Java software package on your computer is a collection of programs and files required to run applications and applets written in the Java programming language. This software package is formally called the "Java Runtime Environment" (JRE.)
Function
-
Java Update periodically checks for newer versions of Java than the version you have on your computer. When a newer version is available, Java Update alerts you. Typically, a pop-up window or balloon on your screen informs you an update is available and gives you the option to install the update or put it off until later. If you click "Install," Java Update automatically downloads and installs the most current version of Java.
-
Benefits
-
Newer versions of Java may include new features, bug fixes (fixes for software errors and problems), and updates to security features that help keep your computer safe. If you want to use applications that take advantage of these new features and fixes, you need to keep Java up-to-date.
Identification
-
The easiest way to find out what version of Java you are running is to visit the "Verify Java Version" page on Oracle's Java.com website. You can also see what version of Java you have installed by looking in your computer's software management tool (such as Windows' "Add or Remove Programs"), where Java is listed as "Java(TM)" plus the version number.
Considerations
-
Java Update downloads the files required to update Java to the current available version over the Internet. The download size is based on the number and type of changes that have been made to Java since the previous version. The download runs in the background, allowing you to keep working on your computer until the update is ready to install. Java Updates may require you to restart your computer when completed.
Recommendation
-
Accept the Java Update every single time or completely uninstall Java. It is better to not have Java on your computer at all than to risk a security breach through an unmaintained version of Java. If you choose to uninstall Java, you will quickly find out if any of your favorite applications or websites use Java. If you discover you need Java, you can download the latest version from the official Java.com website for free.
Warnings
-
If you do not keep Java up-to-date, you may not be able to run your favorite Java-based applications or visit your favorite websites that use Java applets. More critically, your computer may be vulnerable to malicious attacks that take advantage of security weaknesses in older versions of Java.
