With Automatic Updates, Windows XP no longer logs into your account automatically. This is usually caused after the installation of .NET Framework from Microsoft. It creates an additional user account called ASP.NET, which you can see in the Control Panel User Accounts applet.

Click Start, and then click Run. In the Open box, type control userpasswords2, and then click OK. In the dialog box that appears, enable Users must enter a user name and password to use this computer check box, and then click OK.

Use this method only if you've configured the automatic logon using the registry manually. Because, automatic logon procedure using Control Userpasswords2 or using Tweak UI does not involve Winlogon \ DefaultPassword key at all. They are stored in protected area rather.

Open Registry Editor (Regedit.exe) and navigate to :

HKEY_LOCAL_MACHINE \ Software \ Microsoft \ WindowsNT \ CurrentVersion \ Winlogon

Delete the DefaultPassword entry.

Double-click AutoAdminLogon, type 0 in the Value Data box, and then click OK.

MSGina.dll checks the state of the SHIFT key when AutoAdminLogon is 1. If the SHIFT key is held down during the boot process, MSGina.dll will ignore the AutoAdminLogon key value and prompt the user for identification and authentication information interactively. You can use this method to temporarily disable automatic logon at startup.
