You can make an account hidden so that no one knows it exists but you using a little Registry Editing!
When you start up Windows XP, you get a logon screen with all of the accounts that you are able to login to. There are also hidden accounts on your computer that you can't see, and this is how you make your own.
Open the 'Start' menu, select 'Run' and type in 'regedit'.
Expand these folders in order from top to bottom:
HKEY_LOCAL_MACHINE
SOFTWARE
Microsoft
Windows NT
CurrentVersion
Winlogon
SpecialAccounts
UserList
Now that you're in the 'UserList' folder, you can see all of the different accounts that you have made, and are running in the background. These hidden accounts are there for a reason, so don't go messing with them unless you know you're sure you want to.
You may now alter an existing account, or make a new one. To make a new one right-click in the window and select 'New' 'DWORD Value' and the name of the file will be the name of the account. By default the new account is hidden so you don't need to do anything else.
To make existing accounts hidden or visible, right-click the desired account and select 'Modify'. The 'Value data' is either set to a '0' or '1', and I'm sure you've already guessed, '0' = hidden and '1' = visible.
In order to access the hidden accounts you must logout and go back to the logon screen. Once there you must press 'Ctrl+Alt+Delete' two times (2x) and a 'Windows NT' style logon window will appear. Type in the desired account name/password and you're in!
The only side effect to this cool little feature is that when you want to log off. Selecting 'Switch User' when logging off will work, but you will not be able to access you're hidden accounts, you may however still switch between visible accounts. To go from one hidden account to another you must log off of the account completly or you will have to restart the computer to enable hidden accounts again.
