Java software gives you the option to set the Java version parameter for handling the Java applets that run in your Web browser and update your version of Java. If you are not sure what version of Java you are running, you need to check the version of Java software installed on your computer by using the Java Control Panel. By checking the panel settings, you can verify if you need to update your Java software to ensure the support for the Java applets in your Web browser.
Open the "Start" menu and then click "Control Panel." Click on the "Java" icon to open the Java Control Panel window.
Click the "About" button in the "General" tab to see the version of Java software installed on your computer.
Click the "Java" tab and then click "View" in the "Java-Applet Runtime Settings" section of the window. Note the version number in the "Version" column of the "Java Runtime Versions" box and compare the Java Runtime setting with the version of your Java software to see if you need to update your Java software.
