I am a complete novice so please forgive me. My computer is and older one. My OS is Windows XP service pack 2. When I bought my computer it was advertized to have 512 MB RAM. When I got it home and hooked it up it had much less. I suppose this was due to pre-installed programs. I now have 384 MB RAM. I wanted to download an internet security program but was told I did'nt have enough RAM. I thought if I REMOVED some things that I never used, that this would increase my RAM. However, anything I removed did not change the 384 MB that are showing. Question 1: Why not? Question 2: I have a program called "ROXIE EASY CD & DVD Creator 6 that I never use. It says its file size is 706.00 MB. How is that possible?
