Unwanted "Extras"Although most people do not need Java on their computer, there are some programs and games that require Java. In the event you need to continue using Java, How-to Geek discovered a little-known and unpublicized option in the Java Control Panel to suppress the offers for the pre-checked unwanted extras that Oracle has long included with the updates. Although the Ask Toolbar has been removed, tha does not preclude the pre-checked option for some other unnecessary add-on.
Do the following to suppress the sponsor offers:
- Launch the Windows Start menu
- Click on Programs
- Find the Java program listing
- Click Configure Java to launch the Java Control Panel
- Click the Advanced tab and go to the "Miscellaneous" section at the bottom.
- Check the box by the “Suppress sponsor offers when installing or updating Java” option and click OK.
Windows XPFor information on Java support for Windows XP, organizations and individuals who must continue using Windows XP and have Java installed are referred to the Oracle blog post, The future of Java on Windows XP (Henrik on Java).
Java Security RecommendationsFor those people who have desktop applications that require Java and cannot uninstall it, Java can now be disabled in Internet Explorer. See Microsoft Fix it to Disable Java in Internet Explorer.
1) In the Java Control Panel, at minimum, set the security to high.
2) Keep Java disabled until needed. Uncheck the box "Enable Java content in the browser" in the Java Control Panel.
