How to Completely Remove and Uninstall Java From Windows PC

Ads by Google

In the past we have talked about some online services that use the Java Runtime Environment (JRE) to run the server side application on the client side. While talking about them, I might have told you to allow JRE to run on the page. But if I would have been talking about the same services today, I will not ask you to grant those permissions. Rather I will ask you to completely disable or even uninstall Java from the computer.

Confused? Well, blame Java. Lately Java has been getting a lot of vulnerability issues and developers are reporting lot of security loopholes that are exploited by the hackers and malware authors to gain unauthorized access over computers all around the world.

The condition is so bad that the Feds in United States have asked users to completely disable or even uninstall Java from their system due to the security flaw. In recent events, a zero-day Java exploit compromised computers belonging to several Facebook engineers which could have compromised sensitive data. The bottom line is that Java has been the consistent target of attacks, and Oracle isn’t able to patch it in time leaving the vulnerabilities out in the open.

How long are we going to overlook these security issues for a handful of online Java based services? Well, I am not and if you too want to bring an end to it by uninstalling or disabling Java, let’s have a look at the steps to accomplish that.

We will show you the way to completely uninstall Java or just disable it. While the former is an extreme measure, it provides foolproof security from Java vulnerabilities. If you don’t want to completely uninstall Java, you may just disable it from the respective browsers.

Uninstalling Java Completely from Windows

To uninstall Java, open the Windows Control Panel and click on Uninstall a program link.

After the Program and Features window lists all the applications you have installed on your computer, search for Java and uninstall every Java installation and update that’s installed on your computer. If you are a developer and you have installed Java Development Kit (JDK), you might want to omit it. After the program uninstalls, reboot your computer.

You may also use an advanced uninstaller like Revo Uninstaller to do the above. In fact, it migh be a better way to do it.

Disabling Java

If you don’t want to completely uninstall Java and only want to disable it on your default browser, that can also be done. However, covering how to disable Java on all the browsers is beyond the scope of this article. We will see how it can be done on Firefox and Chrome, currently the top two browsers known to us.

Chrome users should write chrome://plugins in the Omnibar and press enter. In the plugin page look for Java and click on the Disable button next to it. Firefox users must open the add-on page by clicking the Firefox button and then disable the Java (TM) Platform plugin from the list. The procedure is quite similar for all the other browsers. You need to open the respective browser plugin page and disable Java from the list.

Conclusion

So that was how you can uninstall and disable Java in your browsers. If you have disabled it you will not be able to run some online apps that require Java Runtime Environment to function. If you have completely uninstalled Java then apart from the online tools that can’t run it, some of the native Windows programs that require JRE will not be able to function. Small price to pay for securing your computer against the deficiencies that Java brings along with it.

    thank you Ashish, really needed that.

    Well, when the “I love you virus” came out did that stopped people from using MS Outlook? No. It forced Microsoft to change the default behavior of outlook of assuming macros were trusted and automatically execute to disable.
    Adobe reader two years ago had many security issues due to trusting embedded scripts. Did that stopped people from exchanging, reading or creating PDFs? No! Did we uninstalled Adobe reader? NO. Adobe came up with a few security patches.
    Microsoft Internet Explorer 6 had more security holes than a Swiss cheese. Did some people stopped using IE? Some did and switched to Firefox or Chrome. Others waited for MS to release a patch.
    Since I’m a Java and Android developer, I need java to compile, so uninstalling is not an option for me, however, disabling it on the browser is a good recommendation.

      You are right and it shouldn’t be like this. But sadly, Oracle hasn’t been as prompt as Adobe and MS in releasing patches. And I am sure you’d agree that Java’s case is different than the ones you mentioned. Java has received much more flak due to its vulnerabilities. Of course, devs like you know your way around all this, but for an average user, uninstalling it is the best option. Apple has recommended it and even the US Feds recommended its uninstallation recently.

      And talking about Java and Android development you don’t need JRE for that. You need Android SDK bundle with Eclipse, Android Development Tools and Java Development Kit.

    removed, thanks……very insightful

    Have read lots of articled re recent hacking. You are the first person to suggest definitive action.
    Unable to comprehend Oracle’s procrastination. Perhaps, if a few more bloggers got together, this could force Oracle into action.

    Uninstalling / Disabling will hamper, besides other, a lot of net banking functions. Are you offering any solution for that? Also, if I have disabled Java and enable it only when doing net banking, and disable it again upon completion, is there still a chance of being hacked? Please advice.

    • http://www.guidingtech.com Abhijeet Mukherjee

      Nilesh, I removed Java from my computer a long time ago and I am able to do netbanking just fine. I think you are confusing Javascript with Java.

      • Nilesh Ashar

        You are right Abhijeet, thank you for your prompt reply. I can still ‘bank’ on my net banking websites. :)

    This is a action a lot more people should take, it just isn’t as secure as it used to be. Maybe I should make a post about this subject too on my blog. Anyway great post :-)

    I haven’t done it yet, and Idk if I should tho, I have it for my online classes. So if I do uninstall, what would be the best program to replace it??? Any suggestions?
