Check "enable third party browser extensions"
(requires a "MUST" immediate restart) ...... Then download java.sun and Install the latest version of sun Java.

JRE 1.5.0_9 available = http://java.sun.com/javase/downloads/index.jsp := http://www.java.com/en/download/index.jsp

Friend,
Look for Java in your Program files and/or try to locate it in find folders option.
You can also try searching in Dos Prompt.Java Script is used by almost 70% of web pages.Windows Xp pro NT provides it as a free inbuilt function.

when required to run a java script, your PC would not run correctly. You can check in control panel if there a icon of java or you can visit http://www.java.com/en/download/index.jsp to download it
