After uninstalling Java, how do I remove its listing in the Windows?
This article applies to:
After Java is uninstalled, Java icon is still visible in the Windows Control Panel
For Windows XP: Add or Remove Programs
For Windows 7: Uninstall programs
The Java uninstaller fails to delete registry entries from the Windows registry during the process of uninstalling Java. Since these registry keys are not removed from the Windows registry, the Java icon is still visible in the Windows Control Panel.
If the Java uninstall process fails to complete then user can manually delete registry entries associated with the Java version from the Windows Registry Editor.
Incorrectly editing your registry may severely damage your system. At the very least, you should back up any valued data from your computer before making changes to the registry.
You can use the File->Export functionality of the registry editor to save the registry key before deleting. Then, in case you deleted the wrong registry key, you can restore the registry from your saved backup file, by using the strong>File->Import functionality in the Windows Registry Editor.
