Legal notices can be set in Windows NT using the following Windows NT registry
add or modify the following values:
|LegalNoticeText||REG_SZ||max 255 chars|
|LogonPrompt||REG_SZ||displayed in standard logon screen|
|Welcome||REG_SZ||displayed in standard logon|
If you want to simulate paragraphs in the Legal Notice text, enter the text
with a space where the paragraph should break. Edit the value using Binary and
replace the space character with 0D00 . Remember that
one letter of normal text is equal to four characters in the binary editor.

- Click Start/Settings/Control Panel
- Double-click Administrative Tools / Local Security Settings / Local Policies

- Set Message text for users attempting to log on

- Logoff/Logon to test

LegalNoticeCaption/LegalNoticeText create a text box displayed prior to logon
which one must respond “OK” to before one can continue the logon process. LogonPrompt is displayed in the standard logon screen

less useful for legal notices purposes). The logon screen variables are
usually used to personalize the logon dialog such as setting the Welcome value
=”Welcome to Wayne’s Computer”. This works in Windows NT, Windows 2000 and
