Pop Up a Banner when Windows Boots

You might want to have a banner pop-up when a user is going to log on, a banner that contains any kind of message you want to display.

Navigate to
HLM\SOFTWARE\Microsoft\WindowsNT\CurrentVersioin\WinLogon

Create a new String Value here called LegalNoticeCaption. Enter whatever you want to see in the bar at the top. Now create another new String Value called LegalNoticeText. Modify it to the message you want to display each time windows boots.
