We have two computers on a home network, using DSL, Windows XP. One is a Compaq Presario 5400US desktop computer, 300+ MB HD available space, 256 RAM (Win. XP Professional). I have removed numerous programs, run Defrag, and a batch program to allow more HD space.

There are several Java 6 updates listed in Control Panel (Add-on/Remove). Is it safe to remove all but the most recent update(s) to increase HD space?
Thanks in advance.
