add-delete programs question

I have a brand new laptop with XP installed on it. I am new to XP as I was
using 98SE before. When I got my new Dell, they had installed Adobe reader,
etc. and I could see them as installed in the Control Panel Add-Delete
programs.

So to my surprise days later when I installed Office 2003, everything was
fine but, somehow, the Office program does not appear in the Control Panel
Add-Delete Programs.They do appear in List- all programs but not in tne
Contreol Panel. Why?? And they seem to work fine. The same thing happened
with all applications i did installed on the laptop. I am confused.
