Here is how to remove the Java listing in Windows Control Panel, which may remain, even after uninstalling Java. You may run this Troubleshooter or manually edit the Registry to remove the old entry.

Last month Oracle released a new Java version, Update 10, that includes a one-stop option for disabling Java in all browsers in the Java Control Panel. Open Control Panel and launch the Java applet.

You can check which Java version is on your Mac to see if you have the most up-to-date Java running, or you can check on the Java website.

Uninstall the old Java versions before installing the new Java package Go to Control Panel. Click on Programs and features. Select Java package and click on uninstall.
