I've recently ( thru the help of an experienced friend and after being attacked by some Trojan? ) re-installed XP Home. Things have been running smoothly


I had to clic the 'login' icon everytime I did something and came back to the desktop so we changed a couple settings in the Display:
I "restarted" last night and now a small window showed up saying I have to enter a username and password for Windows? When/did I during "re-install" have to establish a username and password for Windows??? Was that during the time just before I nodded off?
Regardless.. I can't make use of my "business" computer and it's costing me - none of my 'business' contacts have the email address to this computer.. Help!?
Thanks...
