UPDATE: This tool doesn’t work in version 1607 and later versions of Windows 10. The only workaround is to set a custom picture as the lock screen background and configure Windows 10 to use the same picture for both lock screen and login screen (go to Settings > Personalization > Lock screen > Show lock screen background picture on the sign-in screen).
The login screen has been overhauled in Windows 10. The user picture on the login or logon screen now uses a circular-shaped user profile picture instead of square one. Additionally, the login screen background uses a picture instead of a solid color unlike in the previous Windows version.
As you know, Windows 10’s login screen background looks very similar to the default desktop background. The default login screen background image is pretty cool and is much better than having a solid color. As you likely know, it was impossible to set an image as the login screen background in the previous version of Windows.
While there is an option to set your own picture as lock screen background in Windows 10, there is no setting to change the default login screen background. In other words, Windows 10 doesn’t allow you to change the default login screen background picture with a custom picture.
Although the default background of login screen is nice, many of you might want to replace it with your desired one.
