Programmers use Java throughout all platforms as it’s a programming language that is very flexible. Making sure that your Java is up-to-date helps you to stay a step ahead in keeping your computer safe. Follow the instructions below to check your Java version and make sure that it’s up-to-date on your system. For more information on keeping your computer safe, read our article “Securing Your Digital Fortress

Checking your current version:

  1. Open your favorite browser and go to http://java.com/en/download/installed.jsp (you can just click this link and it will open a new window)
  2. Once the page loads you may have a small bar popup that is requesting your permission to run a plug-in, allow this plug-in to run
  3. You should see a page with a white background and in the middle is a red button, click on the red button
  4. You may once again see a small bar popup asking for permission to run, allow this to run
  5. After the scan is complete it will show the version of Java that is currently running and inform you of the current version
  6. If your system is up-to-date the webpage will show you “Congratulations!” and inform you that your Java is up-to-date. If you get a different message, see below on how to update your Java to the latest version.
Updating to the newest version:
  1. If the version currently running is lower than the latest version published by the people making Java, then there will be a red button in the middle of the page again. This button says “Download Java Now”, click it
  2. The screen should change and a new red button comes up, click the button that says “Agree and Start Free Download”
  3. This will download a small installer executable to your computer that you will need to open once it has finished downloading. Depending on your browser there may be several ways of doing this, but most systems have a “Run” or “Open” option as well as allowing you to double-click the file if you know where it was downloaded to.
  4. The UAC (User Account Control) found in Windows may popup asking for your permission to run the executable, allow it
  5. Once you’ve entered the Java installer, you’ll see a screen that welcomes you to Java and you’ll know you’re in the right place.
  6. When you’re on the welcome screen, simply press the “Install >” button found in the bottom right of the window
  7. You’ll see some windows appear and flash away to finally leave a Java Setup window, this is normal
  8. Once the installer is finished it will show a green check mark and the text “You have successfully installed Java”. Congratulations, you have installed your Java update, click on the “Close” button to finish the process.
  9. Note: You may want to reboot your computer after installing this update to make sure the changes are applied to all applications using Java.
