For some time now, installing/updating Java prompts you to install the Ask.com toolbar and search page. After installation, this is offered each time you install a new update of Java, which can be very annoying. A somewhat undocumented feature is that you can disable these offers from the Java Control Panel, preventing future updates from prompting you to install this thing.

1. Open the Java Control Panel from the Windows Control Panel.
2. Click the tab Advanced, scroll all the way to the bottom.
   There, under the Miscellaneous section, check Suppress sponsor offer when installing or updating Java.
