Enable a Warning Message During Windows Logon

Serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

To enable display of a warning message, make the following changes in the registry:

1. Start Registry Editor (Regedit).

2. Locate the HKEY_LOCAL_MACHINE subtree, and then go to the following key:
SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

3. Add or modify the following values:




For example, the "LegalNoticeCaption" can be "Important Notice:" and the "LegalNoticeText" can be "No unauthorized access is allowed".

The user sees this dialog box after the user presses CTRL+ALT+DEL and before the user sees the logon dialog box. The user can click OK in the message box and log on normally. Quit Registry Editor.
