Need Help - Logged on Win XP

i have win xp Media center edition sp2 on my laptop. now the problem is that every time i restart or resume from hibernate option, the welcome screen shows me 'logged on' always, which i dont want, next when i click my name it asks for my password and logs on.

now what is bothering me is that why does it always show me logged on, even before i enter my password. earlier this does not use to happen, when ever i started my laptop it would directly ask for my password and never showed logged on. this problem started from 2-3 days back, when i networked my laptop with my desktop. all settings and changes were done in desktop, laptop was not touched.

plz help me to just remove that logged on in front of my username from the welcome screen, the welcome screen as earlier should directly ask for my password.

thanks in advance.

 

hello, plz can some one help me, i hope its not a virus...
