How to Uninstall Java from Your PC or Mac

uninstall java

Java is present on most Windows and Mac computers. In the past (and even now) quite a few websites required you to have Java installed to be able to access all of the website’s or Web application’s features. Put it simply, Java was the programming language designed to make the Internet more interactive and more fun. Nevertheless, it is advisable to uninstall Java altogether.

Why you should uninstall Java

Unfortunately, Java has many flaws especially when it comes to security. Today Java is the weakest spot in your PC’s or Mac’s security – it has numerous vulnerabilities that malware developers exploit all the time. While Oracle tries to implement urgent updates, they don’t come in time. And Mac users are even worse off because Apple creates custom Java updates that usually come weeks or even months after Windows users get updates directly from Oracle. 

Of course, keeping your Java patched reduces the security risk. But even that doesn’t guarantee complete security. This is especially true if you use a 64-bit system – even it the 64-bit Java is updated, you are still unprotected if there are any 32-bit Java components on your system.

All things considering, it makes sense to uninstall Java altogether instead of updating it and removing old Java versions (a must when you update Java).

How to uninstall Java

At a glance, Java doesn’t seem too difficult to uninstall. You can remove it just as you would remove any other software. However, there are some things you will need to do afterwards if you are a Windows user.

To uninstall Java:

  1. Click on Start and go to the Control Panel
  2. Now select Programs and go to Programs and Features
  3. Select Java and click on the Uninstall button
  4. Make sure you uninstall all versions
  5. Reboot your PC

After you uninstall Java, you will need to run a registry cleanup tool to remove redundant registry entries that got left by Java. This is very important because  leftover registry entries can be a way for malware to enter your computer. We suggest that you clean your computer with our recommended registry cleanup tool.

Uninstall Java from Mac

Uninstalling Java from Mac is pretty easy. Remember that you need to have administrative privileges, though. Here is what you need to do:

  1. Click on the Finder icon and then go to the Applications tab
  2. Type JavaAppletPlugin.plugin in the Search box
  3. When the Java plugin is found, right-click on it and move it to Trash
  4. We also recommend rebooting your Mac for all changes to take effect
