After recently re-installing XP Pro and all my drivers and then updates I thought all was good. Then I was just checking everything out and I noticed that in my Add/Remove programs listing there is nothing showing up. This is not the first time I have installed this particular version of XP Pro. It is a bought and paid for Copy,bought through Newegg in 2004. With having upgraded hardware over the years I have re-installed this version a few times and this is the first time I have run into this problem. What would have caused this to happen and is there a fix for it without having to re-install again?
