How to Add Administrator Account to Log In Screen?

Before you try out the Tweaks, Please Backup Your Registry..

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.

[Start] [Run] [Regedit]
