Looking for a way to get rid of Java on your Windows or Mac machine? Though essential to some web users, most people do not need to risk running Java on their machines because of all the security vulnerabilities associated with Java.
In this article, I’m going to talk about the steps you need to take in order to completely remove all traces of Java from your Windows machine. The process for Mac is a bit different, so you can scroll down the Remove Java on Mac section if you are running OS X.
Note that the newer versions of Java (Java 8v20 and higher) have a built-in tool for uninstalling older Java versions automatically, but sometimes even this tool doesn’t get rid of everything. Also, it keeps the latest version installed, which you might not want either.
Is Java Installed?
You can check whether you have Java installed or not in Windows by going to the Control Panel and looking for the Java icon. If you see it there, that means you have Java installed.
Using this Control Panel option, you can also disable Java in your web browser without uninstalling it. I’ll explain that option below also. https://roacipe.hatenablog.com/entry/2020/11/23/091448. If you go back to the Control Panel and click on Programs and Features, you can see all the different versions of Java installed on your computer.
So what’s next? Well, the first thing I do when removing Java on Windows is to uninstall the older versions first.
Remove Older Versions of Java
If you simply enable Java without knowing this, you’re likely to be enabling malware to run on your computer – which would be so dumb as to be eye-watering. Head over to the Java website, then download and install Java.
To get rid of the older versions, you can download and install the latest version of Java, which will automatically check for older versions and then install the latest version or you can run the Java Uninstall Tool.
The applet will check your version of Java and then remove out-of-date versions. If there are older versions, you will get a message showing you the versions and giving you the ability to uninstall them.
Click on the Uninstall Selected Versions button to remove the older versions. As you can see, I don’t need Java 8 Update 60 because I have the latest Java 8 Update 65 installed. Now that you only have the latest version, we can do one of two things: either disable Java or uninstall it.
Disable Java
If you need to occasionally use Java for certain websites, but don’t need it enabled all the time, you can disable it instead of uninstalling. To do this, open the Control Panel, click on Java and then click on the Security tab.
Uncheck the Enable Java content in the browser box to disable Java in Internet Explorer. It’s worth noting that Chrome doesn’t even support Java anymore since version 42, so you don’t have to worry about it in that browser.
For Firefox, you have to click on Tools, then Add-ons and select Plugins. Click on Java Platform and then click on Disable. Note that even though Java is disabled, it can become outdated and still present a security vulnerability to your computer since it is installed.
Uninstall Java in Windows
To uninstall Java, first remove the older versions like shown above and then go to Control Panel and Programs and Features. Click on the latest Java version listed there and click on Uninstall.
Technically, this is all you should have to do, but if you really want to get rid of every trace of Java, I recommend using a freeware app called JavaRa. Once you download it, just run the application. You’ll see a couple of icons, but the one we want to use is Remove Java Runtime.
On the first screen, it’ll show you that the uninstaller was not found, which is fine since we uninstalled all versions of Java. Just click on the Next button.
The most important part of this program is Step 2. Here you want to click the Perform Removal Routine button, which will remove any leftover files, folders and Java registry entries.
Even after uninstalling Java using its own tools, JavaRa was able to remove 12 more items that were left behind.
Click Next and you’ll see a button to download the latest version. Unless you want to reinstall Java, just click Next and then click Finish on the next screen. Now Java is completely removed from your Windows system.
Remove Java on Mac
On Macs, everything is pretty much the same, except for the uninstall process. You can see whether Java is installed on your Mac in pretty much the same way as Windows. Just open up System Preferences and check to see if there is a Java icon at the bottom.
If the Java icon is there, that means you have Java installed on OS X. Also, just as in Windows, you can choose to keep Java installed, but disable it in Safari if you like. The first way is to click on the Java icon in System Preferences, which will open the Java Control Panel, which looks exactly like the one in Windows. Click on the Security tab and then uncheck the Enable Java content in browser box.
The other way is to disable Java in Safari directly. To do that, open Safari and then go to Preferences.
Click on the Security tab and then click on the Plug-in Settings button at the very bottom next to Internet plug-ins.
You should see Java in the list and unchecking the box will disable Java in Safari. If you want to uninstall Java on OS X, it’s a bit technical. First, open up the Terminal by clicking on Spotlight and typing in Terminal or by going to Applications – Utilities and then Terminal.
Now copy and paste in the following commands one at a time and press Enter after pasting each command. Windows ubuntu usb creator tool for mac.
When you press enter, you will be asked to enter your administrator password. If everything went well, you won’t see any output.
If you go and check in System Preferences, the Java icon should be gone. Also, if you go to the plugins section in Safari, it will also be gone from the list of installed plugins. That’s about it for removing Java on Macs. If you have any questions, feel free to post a comment. Enjoy!

What is finder app on mac. Robert Vallee wrote in with a simple request related to a Java dialog that keeps appearing: Autocad 2010 64bit crack keygen.
How to get rid of this sticky pop-up window that’s coming on and on?
The popup dialog is maddening from several standpoints:
Robert, I feel for you, because ever since I installed Yosemite, I’ve had this problem off and on. I managed to solve it for Yosemite somehow—I still don’t know how—and then it appeared again once I’d installed an El Capitan public beta. Recently, I managed again to get rid of it, and again don’t know how, after weeks of having it crop up multiple times a day.
The good news is that you can ignore it. Click OK, and forget it. The bad news is it’s so annoying and intrusive. Apple unfortunately doesn’t provide an option to disable the dialog, even though OS X is creating it. Apple stopped including Java after Mountain Lion, but makes a special legacy version available.
Java had enough security flaws in its use via websites and zero advantages for Mac users that Apple updated Lion and Mountain Lion to disable its use in browsers. But some cross-platforms “Mac” apps are really just Java packaged in a form that can run in OS X. CrashPlan for OS X remains Java based, although the company reformulated its distribution to incorporate the Java runtime engine inside the software package. (If you have a Java preference pane, you can go there to make sure your security settings are the way you like, especially keeping it from running in a browser.)
But if you launch a program that requires Java, it tells you explicitly. The dialog that drives Robert, me, and many others batty appears without enough information upon which to act.
After scouring the Internet for advice over the last year, I have several suggestions of what to try.
Check the Users & Groups system preferences: Select your user name in the list (if it isn’t already) and then click Login Items. You may need to authenticate your account to proceed. Most apps have migrated away from using Login Items to launch background agents; they should use a different process that’s more reliable and recommended.

In my list, I have only one app I want to launch; EyeTV is the only package that has a “helper” app that also runs at launch. If you see anything odd here you no longer use, select it and click the minus sign (-) to remove it.
Some people have reported that outdated Adobe Creative Suite agents were in this list long after they’d stopped using a given version, and suggest removing those as it solved their problems. Some older web-development software, such as earlier versions of Dreamweaver, may require an OS X-based Java installation. Qoppa’s PDF modules and software use Java, too, and may be the reason some users see a dialog on older systems.
Outdated launch agents, daemons, and plug-ins: OS X allows software to drop in a variety of tools to have the system launch components as needed. You may have a component that gets triggered from the Finder or other background processes that’s ancient and tucked away in. In the Finder, select Go > Go To Folder (Command-Shift-G) and paste in each of the following in turn:
/Library/LaunchAgents /Library/LaunchDaemons /Library/Internet Plug-Ins
Those are globally available items for all users; add a tilde (~) in front, like
~Library/ and you can check the same subfolders in your own user account. You may find all sorts of nonsense in there. I found items dating back years. Some will no longer do anything; others are chewing up a little of your processor time in the background, eternally.
Select the ones you’re sure you don’t and move them to the trash. You may need to authenticate your account to complete the operation.
See what software uses Java: If none of this worked, you should examine your Applications folder to figure out if there’s something hiding there that could be the culprit.
A clever member of the Apple Forums suggested a lengthy Terminal-entered command that will provide a summary (after up to a few minutes of chugging away) of all the apps that have Java components. Copy the entire following line and enter it at a Terminal prompt: Quick access tool bar in excell 2013 for mac.
find /Applications -type d -name *.app -prune -exec sh -c 'ls -R '$1' | grep -q .jar$' {} {} ; -print
Not all these apps use Java, but all of them contain some Java components, some of which could be activated when the program is in use or when it’s in the background. And some may include the full Java runtime, as CrashPlan does.
Unfortunately, you may still see the dialog box after trying all of the above. Let us know in the comments or at [email protected] what worked and what didn’t.
Thanks to Cynthia D’Angelo for patiently testing out over a dozen potential fixes in the hopes of removing her own dialog box. None worked so far!
