How to Disable Java Updates in Windows 7
Originally developed by Sun Microsystems, and now maintained by the Oracle Corporation, the Java programming language allows software developers to create programs capable of running on any operating system with the Java Runtime Environment package installed. By default, Java updates are automatically enabled when you install this software on your Windows 7 machine. If you do not want to be bothered by update notifications each time you turn on your computer, you can disable the display of these messages with just a few clicks.
Click the Windows "Start" button and select the "Control Panel" item.
Type "Java" in the search box located at the top-right corner of the window.
Click the "Java" link that appears in the list of search results. The Java Control Panel window will open on your screen within a few seconds.
Select the "Update" tab from the top of the Java Control Panel window.
Uncheck the box labeled "Check for Updates Automatically."
Click "Never Check" when prompted to confirm your choice.
Click "OK" to save your changes and close the Java Control Panel.
