Correct uninstallation of Java

Oracle, which develops and maintains this executable package, has met users halfway and released a special tool for removing old versions called the Java Uninstall Tool. You can do without this utility by removing the package manually using system tools or using an application for uninstalling programs.

Java Uninstall Tool

The easiest and most convenient way to remove Java from your computer once and for all is to use a special utility.

Java Uninstall Tool download page

1. Open any suitable browser and follow the link above. Find and click the “I accept the terms and conditions and want to continue” button. If you would like to read the license terms, there is a link to the text below the button.
2. Save the utility executable file to your hard drive. Once the download is complete, close your browser, navigate to the location of the downloaded file, and run it.

   Please note that your account must have administrator rights to use this tool.

3. In the start window of the utility, click on the “Agree” button.
4. A warning appears indicating that only the latest version of Java is detected on your computer. Click “Yes”, since this is the one that should be deleted.
5. In this window you will need to select the version that will be uninstalled. As a rule, there should be only one item in the list - mark it and click “Next”.
6. Another warning will appear, in which you also click “Yes”.
7. Next, you will be asked to delete the cache of Java-related applications. As a rule, without the package itself it is useless, so feel free to click “Yes”.
8. Wait a while for the utility to do its job. When the procedure is complete, click “Close” to close the application and restart your computer.

Done – Java SE Runtime is completely removed from your computer. We recommend using this method, since the utility also removes traces of Java from the system registry, which is not always possible to achieve with manual removal.

Uninstalling Java using a third-party uninstaller utility

In addition to standard Windows tools and a program from the developer, you can use third-party software to remove Java, for example, the free Russian-language utility “Revo Uninstaller Free”, which can be downloaded from the official website https://www.revouninstaller.com/products/revo-uninstaller-free /.

1. Follow the link and after the page has opened in the browser, click the “Download” button. After downloading the program distribution kit, install it on your computer. It is also possible to download a version that does not require installation by clicking the “Download free portable” button on the program download page.

2. Launch Revo Uninstaller, find Java in the list of installed programs and click the “Uninstall” button on the panel at the top of the window.

   Select Java and click on the “Delete” button

3. The program will create a system restore point and perform other preparatory steps. Then the screen will ask: “Are you sure you want to remove this product?” We answer “Yes”, after which the uninstallation process will start.

   Click the “Yes” button to start deleting

4. Once the Java application is uninstalled, select the scan mode and click the Scan button. Revo Uninstaller will check to see if any files, folders of the deleted program or entries about it remain in the Windows registry after uninstallation. Most often, the utility performs a clean uninstall and displays a message that the remaining data was not found.

We talked about four options for removing Java from your computer: standard Windows 10 tools are faster, since they are always at hand, and software from the developer or a third-party uninstaller utility will first have to be downloaded to your computer. However, third-party solutions work more efficiently and do not leave traces of the uninstalled program on the system. Which method to use is up to you.

The Java platform is the No. 1 environment among software developers for computers and portable devices due to the simple architecture of the programming language of the same name and the translation of executable code into specialized bytecode. Thanks to this capability, software developed using Java can run on virtually any device or virtual machine. As a result, the library that provides support for the technology must be installed on any user’s computer controlled by Windows 7.

Due to the constant improvement of technology, its developers release new versions of the environment, execution module and plug-ins from month to month. They include both completely new and updated components. An update most often means improving security and performance, correcting detected problems, and optimizing executable code.

Before updating Java, developers recommend uninstalling the old version of the product from Windows 7 in order to avoid conflicts or the inability to replace one of the files due to its use by third-party software (browser) and to ensure that programs work using a completely updated environment.

What’s noteworthy is that starting with revision number 45, Google Chrome stopped supporting NPAPI for Java applets.
