You might be the only USER but are you the only one who might have ACCESS?
Do you have confidential information on it? You need to think of the
security implications before you do this.

I agree with Gordon. It may be convenient not to have to sign in at the
Welcome Screen but it also means that anyone who finds, steals or
invades your laptop has the same easy access.

How to do this?  
or
Whether to do this?  

Here's HOW to do this:  Method A:  Download TweakUI and look under
LOGON and check the box so you don't get a Welcome screen.  TweakUI is
available from Microsoft.  It's a "Powertoy" A search on Downloads
should find it.  

There are other Methods, but I don't know them.  The two other posters
know them, but I don't know if they'll tell you or not.  Only certain
people get to have their questions answered directly.  <g>

Start | Run, type "control userpasswords2" Select the account you want
to logon to automatically. Then uncheck the box "Users must enter a
user name and password to use this computer."

Or do the same thing with TweakUI.

1. Go to Start/Run and type in:  control userpasswords2 and press ok.

2. On the Users tab, left click "your user name" then clear the Users Must
Enter A User Name And Password To Use This Computer check box and then click
OK.

3. In the Automatically Log On dialog box that appears, type the "user name
and password" for the account you want to be logged on each time you start
your computer.

Added note:  (Alex MVP)

If you want to logon to one of the other users, hold down shift as the
system boots up.

Tip:

Add Control UserPasswords2 to the Control Panel (Line 1)
