Enable Ctrl+Alt+Delete for Vista Logon Screen

Control-Alt-Delete (often abbreviated to Ctrl-Alt-Del) also known as the "three-finger salute" is a keyboard command on systems that can be used to reboot the computer. It is summoned by pressing the Delete key while holding the Control and Alt keys. It brings the task manager or Windows Security in more recent versions of the operating systems produced by Microsoft Windows. It can also be used to logon to a computer.

Windows Vista logon is Name and icon style logon. In the earlier Windows a user had to press the Ctrl+Alt+Delete keys to logon to a computer. If you are a fan of the older style logon you can do the following to enable this type of logon on Windows Vista. According to some people Vista’s logon can have security issues that can be prevented if you enable Ctrl+Alt+Delete when logging on.

First you will need to clear out the username field. In this way it will show you a blank username and password screen when logging in. The registry trick will do the job. Just follow it HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionPoliciesSystem. There you will need to find the value named ‘DontDisplayLastUserName’ and you will need to set it to 1. If you don’t see it, then you will need to create a new DWORD item with this value. Now your logon will have two slots one for username and one for password.

Now you need to enable the CTRL-ALT-DEL screen. This can be enabled by following the key “HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrentVersionWinlogon”. There you will need to find the value named “DisableCAD’ and set it to 0. If you don’t see it, again you will have to create a new DWORD item with this value. That’s all and now when you get to the login screen you will be required to hit CTRL-ALT-DEL to login.
