This article explains how to change the Windows 10 login screen in Windows settings.
How do I change the background of the Windows 10 login screen?
The Windows 10 sign-in screen, often referred to as the login screen, is the screen that appears after the lock screen when you turn on your Windows 10 device and swipe up on the screen or press a key on the keyboard.
While most people only see the Windows 10 login screen for a few seconds as they type in their password or sign in with Windows Hello, many eventually want to change the default Windows logo background to something a little more personal.
Changing your login screen image is easy, allowing users to change this setting quickly and as often as they like.
