Hi, Just a few simple questions about the best overall software maintenance downloads for XP Pro SP3. I am running XP Pro on an older IBM ThinkPad Z60t. Currently, I am using the free addition of Advanced System Care for everyday maintenance. It seems to be quite good, but is there something better (and free) that I am overlooking? I am a rank novice at the tech game so I gotta keep it a bit simple for now. Any good ideas?
