I am speaking with respect to Java for Windows. Improve this question. Add a comment. Active Oldest Votes. Should I uninstall older versions of Java? Improve this answer. But why doesn't the update remove the older version for you? Or upgrade over the previous version. There must be a reason that it does leave the old version in place, even if its removal is recommended I was also wondering why they don't put a configurable option for whether you want to automatically uninstall the older versions or updates.
It's cumbersome to do manual uninstallations after each auto update The available JREs in this list are encoded in the deployment. For uninstalling the older Java versions or updates, Oracle has released a separate application for uninstalling out-of-date versions of Java called Java Uninstall Tool for Windows — karel. It does remove older versions. Much older installers did not, but newer ones do.
Also, the installer can be given an option that marks the installation as pinned. Future installers won't uninstall that version. This feature is intended for applications that require a specific version of java. Also, java versions that were installed before they changed the behavior to uninstall old versions will not be uninstalled. So at least one round of cleanup will be necessary if you have older versions that you don't need. Show 2 more comments.

It didn't come with it, but one day it popped up and asked me to download it. That is why I questioning the need of this device in my computer.. I gotten many responses saying that, I need it, and how to download it, but nobody tells me exactly which files need it.
I have read everything I found available in the internet, about it, but it is all the same, and I still don't know the answer to what I am asking. So, I still don't know what to do. I guess I will leave alone for now. If I ever have to tune up this machine, I will leave Java out and see what happens. Choose where you want to search below Search Search the Community.

If I remove the last update, will it go back to what it was there before? Would it hurt anything if I just completly remove Java from my computer? This thread is locked.

Hi Rosey21, Thank you for the detailed information. How satisfied are you with this reply?
I therefore regard Java as an unnecessary security risk, and I removed it from our home PCs years ago. I suggest you do the same. Living without Java is much less of a challenge than living without Adobe Flash. All programs have bugs and may have security holes, so why the Draconian approach? Sorry to say, I don't have enough confidence in Oracle's ability to fix it. Oracle didn't write Java, just inherited it when it bought the failing Sun Microsystems, and according to The Register : " Metasploit founder HD Moore warned Oracle was still sitting on a backlog of Java flaws that will take up to two years to patch, even without the discovery of new flaws.
Oracle is good at selling high-priced products to large enterprises, but Java involves dealing with up to a billion non-paying consumers.
In my view, Oracle's belated response to the recent "veritable media firestorm" does not make the right noises about protecting consumers. It seems more concerned with defending its profit-making server-side and embedded Java businesses. So, start by disabling Java in all your browsers. Sophos's Naked Security blog has instructions for most popular browsers.
I also recommend uninstalling any other versions of Java that you can find via the Windows Control Panel. You may find three or four: in my experience, old versions of Java are not always removed. After that, run the free CCleaner program to clear out any bits left behind. If you don't have CCleaner, download it from piriform. Next, go to the java. If you know you must have Java installed, you can now do a clean installation of the latest version, either Java 6 to Update 39, or Java 7 Update Java 6 is on the way out and won't be updated again.
Some companies have stuck with it, possibly because of Java 7's terrible security reputation, but it has most of the same vulnerabilities. If you are not sure you need Java, try running your PC for a few weeks to see if you can do without it.
You will get a notification from any website that needs a Java browser plug-in.
