Hi,    At first when I started using XP I was logging on without needing the password THOUGH I'm not sure that I was the Adm. or not, but as soon as, I made a password for the Adm.  I now log on as Adm. and need to give the  password.  I've read in Windows help that I shouldn't log on as Adm. because of the GREATER damage a Trojan can do to my computer because I'm logged on as the Adm. 

So I need help to first to stop logging on as the Adm.  and secondly I need to know how to become the Adm. when needed.  Right now I have just the Adm. USER and a guest user.

Not sure what to do.  I did search for this answer.  Thanks for your help You need to create a NEW user profile.

1.  click Start, and the click Control Panel

2.  Click User Accounts
 
3.  Click Create a new Account

4.  The system will ask you for a name for the new user then what rights you want to give the new user and here you can chose to not give it administrator rights.

When you need to be administrator you can log in under the original user.  Which you would have to be in order to perform any updates or downloads.
