How to Add a Unique Login Message on Windows 11

Want a special hello from your PC when you log on? Here’s how to add a custom login message on Windows 11.

Group Policy Editor includes an Interactive logon policy option users can enable to create custom login messages. With that policy setting enabled, a PC will display a custom login message just before its users sign in to Windows 11. However, Windows 11 Home edition doesn’t include Group Policy Editor.

So, that must mean that this customization setting is only available for Pro and Enterprise users only, right? Wrong; Home users can also add unique login messages to Windows 11 without Group Policy Editor. This is how you can add a custom login message in any Windows 11 edition.

How to Add a Login Message to Windows 11 by Editing the Registry

The Windows registry includes legalnoticecaption and legalnoticetext string values. You can add custom login messages to Windows 11 by manually modifying those string values with the Registry Editor. Daunting though that might sound, it’s quite straightforward to apply that registry tweak. To do so, follow these steps exactly as specified.

  1. Click the taskbar’s search button, and enter the keyword Registry Editor there.
  2. Select the Run as administrator option for the Registry Editor search result to open that app with elevated rights.
  3. Now input the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System registry key location in the address bar. Alternatively, you can click that location’s different keys within the Registry Editor’s left sidebar.
  4. Look for and double-click the System key’s legalnoticecaption string value.
