I have a work laptop, HP Elitebook 8440p running windows 7 enterprise.
In the past week java.exe has recently been using Long bursts (around 5, 10 minutes) of 25% cpu.

I have admin rights and have upgraded java today but it still does it.

How can i find out why and what to do about it?

Cheers

I'd suggest step 1 is figuring out what that Java process is doing.

To do that - launch Task Manager.  Then choose "Select Columns" from the view menu and select "Command Line arguments".

Now you can find the Java.exe process and it will show you a full command line for how it was launched.  Seeing that may immediately give you a hint about what it's doing but if not you can post that here and we may be able to help.

You are also going to want to check through the various programs that are started up when your system launches to see if one of them is running Java.  The tool to use is called "MSConfig" (comes with Windows), some details here:
