Create a Hidden User Account

This tweak allows an account that is normally displayed on the Welcome screen to be hidden from view. To log on using the account it's necessary to use the Log On To Windows dialog box similar to the one in Windows 2000 i.e. press CTRL+ALT+DEL twice.

[Start] [Run] [Regedit]

Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon\SpecialAccounts\UserList
Setting for Value Data: [0 = Account is Hidden / 1 = Enabled]

Exit Registry / Reboot

While the account is hidden on the Welcome screen, note that the account profile will be visible in C:\Documents and Settings or wherever user profiles are stored as well as in Local Users and Groups.

Add Administrator Account to Log In Screen

When Windows XP is first installed it requires you to enter at least one name of a user who will access the computer. Once you create this name the default Administrator account vanishes. To access it, press Ctrl-Alt-Delete twice at the Welcome screen to retrieve the standard Windows 2000 logon dialog. Log on as Administrator from this point. To log the Administrator off, click [Start] [Log Off] and [Log Off] when the [Log Off Windows] selection box appears. The Log On screen with the available users will be displayed.

To Make the Administrator Account Always Visible on the Login Screen use this Registry Tweak.
