Safest way to set up user profiles in Win XP

H there,

I had been using my own user profile for admin as well (some people say it's safe and some people not, Dell said it's fine) but a friend again advised me I should set up a separate admin profile and make mine limited so I am not vulnerable while surfing the net.

I set up a new admin account and changed mine to limited, however some but not all of the programs came up in the new admin profile. For example, when I go to ad/remove programs in the new admin profile nothing came up.

Q1. Is there a simple way I can tell my admin profile to find all programs so I can edit them from there instead of my user profile?

Second question - I had been having a lot of DCOM Exploit attacks and so went through the Dcombobulator process only to find my 153 port is STEALTH. As I'm not sure what this actually means, (did not understand the explanation although I read it twice) I pressed Dcombobulate. It still comes up as stealth though.

Q2. Is this something to worry about?

Thanks,
:confused
