When you invoke the SAS (Secure Attention Sequence (CTRL+ALT+DEL)), the title of the dialog box is:

      From the Welcome to Windows screen      Log On to Windows
      When you are already logged on      Windows Security

You can append information to these titles:

1. Use the registry editor to navigate to:

        HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

2. Add value name Welcome, a string (REG_SZ) data type, and type the text you wish to append.

3. If you typed:

  - JSI, Inc.

invoking the SAS while you are logged on would display:

Windows Security - JSI, Inc.
