This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs.

The Windows Setup program configures Microsoft Windows XP to use the friendly Welcome logon screen and the shutdown buttons if your computer is installed as a home computer. A home computer is a computer that does not specify a network domain.

This article describes how to use the classic logon screen that Windows XP-based computers use when they are joined to a domain. The classic logon screen looks similar to the following example: Log On to Windows
User name: _____________
Password: _____________

Use the classic logon screen
To temporarily use the classic logon screen, press CTRL+ALT+DEL two times on the Welcome logon screen.

To configure Windows XP to use the classic logon and shutdown screens for every logon session, follow these steps:1. Click Start, and then click Control Panel.
2. Double-click User Accounts.
3. Click Change the way users log on or off.
4. Clear the Use the Welcome screen check box.
Note If you turn off the Welcome logon screen, you also turn off the Fast User Switching option.

Require users to press CTRL+ALT+DEL before the classic logon screen appears
Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

If you want users to have to press CTRL+ALT+DEL before the classic logon appears like a Windows XP-based computer that is joined to a domain, follow these steps:1. Click Start, click Run, type regedit in the Open box, and then click OK.
2. Click the Winlogon subkey at the following registry location:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
3. Click Edit, click New, and then click DWORD value.
4. To change the value name, type DisableCAD, and then press ENTER.
5. Keep the data value set to 0. The data value set appears as 0x00000000(0).
