Legal Notice pop-up on windows

If you want to pop up a message box when your computer starts and before the logon screen on Win9X or WinNT, then you can use this trick.

Run the Registry Editor using Start->Run and then type "regedit" and Enter.
You will come up with a windows with title Registry Editor. You will see that something like this.

Here is a view of Registry editor.
On the left pane we have a tree view with some items. These are actually the roots of different types of keys.

HKEY_CURRENT_USER holds the information about the currently logged on user.

HKEY_LOCAL_MACHINE holds the information about the whole computer.

Go to:

For Win9X

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\WinLogOn

And For WinNT

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\WinLogOn

And make two String Keys named

LegalNoticeCaption and LegalNoticeText

(On Windows Server 2003 these strings already exist)

Put any value which you want to display. First is the Title of the Message box and second is the text to be displayed. After doing this, you will get welcome message each time windows starts.

NOTE: Modifying the registry is dangerous. If you make any mistake you may corrupt your registry. This may cause your system to crash or become unstable.

Example message Windows 2000 / 2003

Example message windows 2008 (in 2008 there’s no pop-up)
