Do not click on my user account to start

[Benjamin]

After changing disk drive and thus reloading Windows XP, when I start my laptop I have to click on my account, whereas before I did not do so. Being single user, I searched in the management of user accounts how to eliminate this step, but after trying every combination I seek assistance.
Only my account appears at the opening, but in user accounts there are three accounts: the mine, an account ASP.NET Machine A. and a guest account activated. Perhaps it should delete the account ASP.NET but I do not know what is its function.
Thank you for your advice

Type:

control userpasswords2

in RUN dialog box and uncheck the checkbox saying:

Users must enter a username & password to use this computer.

1) Click Start, click Run, and type control userpasswords2. This is a shortcut instead of having to click on Start -> Control Panel -> User Accounts.

2) Uncheck the "Users must enter a username and password to use this computer" check box. Click Apply.

3) Enter the user name and password you wish to automatically log on with, and then click OK.

4) Click OK again and you're all done.

if u dont hav pass u wudnt need the 3rd step.

Delete the account ASP.NET cause it is created automatically when you install Net Framework, it can be safely deleted.
