Display custom legal notices & start up messages in Windows 10/8/7

Startup messages let you display a reminder or any important message, every time users log into a Windows computer. As a company, some may even choose to display legal notices on every start-up. The process of displaying a startup Message Box in Windows 8 is basically similar to what it was in Windows 10/8/7. You can do so via the Group Policy Editor or the Registry Editor. Let us see how to do it!

Deploy legal message on start-up in Windows

Using Windows Registry

To do so, press Win+R in combination to show up the ‘Run’ dialog box. In the empty field of run dialog box, type the following keyword – regedit and hit the ‘OK’ button.

registry editor

Next, when in the ‘Registry Editor’ window, navigate to the following key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version\Policies\System

Registry Editor window

Under this key, you will notice two entries. It is these entries that need modification, to activate a start-up message:

  1.     legalnoticecaption
  2.     legalnoticetext

For doing so, right-click on the each of them, one after the other and choose the ‘Modify’ option.

It is first essential to understand the function of these two values. The first one, i.e., the legalnoticecaption value controls the title of the message. The message appears in a large font on your computer screen.

The second one, i.e., the legalnoticetext value, controls the body of the message. It can be seen below the title. It is this place wherein you can enter any additional information to be displayed in your message.

Legal warning

Click OK and Exit.

Using Group Policy

If your edition has the Group Policy Editor, you can also do so by navigating to the following folder:

Configuration\Windows Settings \Security Settings\Local Policies\Security Options


Here you will see two entries:

Interactive logon: Message title for users attempting to log on. This security setting allows the specification of a title to appear in the title bar of the window that contains the Interactive logon: Message text for users attempting to log on.

Interactive logon: Message text for users attempting to log on. This security setting specifies a text message that is displayed to users when they log on. This text is often used for legal reasons, for example, to warn users about the ramifications of misusing company information or to warn them that their actions may be audited.

Double-click on each of them and in the window which opens, enter the title or the text, as the case may be. Click Apply/OK/Exit.

Your Windows computer will display the start-up message, every time you turn it on.


 To undo the setting, simply reverse the changes made.
