Java is a widely used programming language that is used on computers, tablets, phones, and even appliances such as your refrigerator. I will explain all of this in more detail below.

Java is meant to be backwards compatible), though the only way to know is through trial and error. Generally speaking, uninstalling older versions of Java is recommended for security reasons and should not impact the programs that require Java to operate (I.E.: The simple answer is: Yes, it is possible to remove older Java updates, and there is an automated way to do this safely (explained below). Therefore, I haveįour questions: is it safe to remove old Java updates? If so, which Java updates can I uninstall? Can I remove older Java versions? Is the latest Java backwards

I regularly receive messages from the Windows 10 Action Center that there is a new Java update available and that I need to download it due to security updates, which I always do. Administrator privileges are required in Vista and 7 (right click, “Run as Administrator”).The other day I went to uninstall a program on my Windows 10 PC using Control Panel -> Programs and Features, and noticed there were about 20 or more Java updates installed on my system.

JavaRa is a small, portable and free utility that works with Windows XP, Windows Vista and Windows 7. There is an “ Additional tasks” button which hosts a few other options such as removing the Java entry from the Windows startup, removing the Sun/Oracle download manager which is included in JRE, checking the current Java installed version, and removing the Internet Explorer Browser Helper Object etc. Before you use this option, it is recommended to close any Internet Explorer windows currently open. This is obviously good for security, gives you a few Megabytes of free space, and removes some useless registry keys. The “ Remove older Versions” button does this and you will be showed a text log file on completion with information about what files and registry entries have been removed. The other main function of JavaRa is to purge the system of all old Java installation files leaving just the newest version. When you click on the “ Search for Updates” button, you have the choice of trying to update using your installed JavaRE’s jucheck.exe updater tool, or via the Java website. One of the primary tasks of JavaRa is to make sure you have the latest version of the Java Runtime Environment installed. This does though, seem to cause more problems than it solves by keeping them around in my experience, and it’s likely to be a better idea to remove them.Ī little utility to help you sort this out by removing the older and therefore redundant Java releases is JavaRa. The latest release of the Java Runtime Environment is always supposed to be compatible with previous versions, but Oracle say it’s not a problem to keep older versions for maximum compatibility. Then you have no option but to go through the removal process yourself to get rid of all the JavaRE installs. This isn’t particularly good for security having the older versions still lingering on the computer, because they may have been replaced due to severe security issues.It’s not unusual to see several different Java versions still existing on the same machine and in some cases Java gets a bit confused with itself about which version it’s actually running, and in turn, this causes it to not function correctly.

The problem has always been with Java, that when you install a new version, the older version it replaces does not get automatically uninstalled and you are left with more than one version on your system.

Java is no different to other software and needs bugs fixing, code optimizing and security vulnerabilities repaired from time to time. As is the case with most software that is used on the internet like web browsers, security software and Windows itself, the Java Runtime Environment (JRE) is updated at regular intervals as well.
