How does the Java Uninstall tool work?

  1. The tool web page checks to see that you are on a supported system (Windows), and if not, you will see a message that indicates your system is not supported and provides links to manual uninstall instructions.
  2. After agreeing to the terms of use for the tool, you will be downloading the executable, JavaUninstallTool.exe.
  3. When the tool is started, you may be presented with the Windows User Account Control (UAC) dialog asking if you would like to run the Java Uninstall Tool. If you see this prompt, click the Run button to load the tool.
  4. The tool checks to see if there are Java versions that can be removed. If there are none, you will see a message that there are no versions of Java on your computer, otherwise you will be presented with a list of versions and if you click Uninstall Selected Versions, the process to remove them begins.
  5. While Java versions are being uninstalled, a progress bar is displayed.
  6. When the uninstallation of all selected Java versions has completed, this tool will list successfully uninstalled Java versions and any remaining out-of-date and up-to-date Java versions. If all the selected versions could not be uninstalled successfully, a message with list of failed versions will be displayed. Uninstalled versions are also written to a log file, along with any errors encountered when running the tool.

Why does the tool require an internet connection?

The tool requires an internet connection because it checks for the latest version of the tool.
