desired display msg at logon

If you'd like your computer to display a message when it starts up, there's a simple registry edit that can do the job for you:

Open REGEDIT.

Navigate to HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/WindowsNT/CurrentVersion/Winlogon

Edit the key 'legalnoticecaption' with the name you wish to call the Window the message pops up in.

Edit the key 'legalnoticetext' with the test you want to put in the message window.
