My machine has been painfully slow recently

I noticed a helpfully named "java.exe" was using 200MB. Killing it using the Task Manager proved useless as it was a service and would restart. So how do you find which service it is?

Simple using wmi, fire up a command prompt, run wimc enter the command 'process where name="java.exe"' and you get the caption and the commandline

java.exe "C:\tools\Cruise Server\jre\bin\java" -Xms512m -Xmx1024m

Which I installed to trial but I haven't yet had the time to do so

Interestingly when I switched it off the Page File Usage on my machine halved
