Many users of Windows 10 they are not happy with the new login screen of their operating system. For those who don't know, the login screen of the windows 10, displays the “Windows 10 Hero” icon in blue photo with rays of light coming from the Windows logo. 
The new operating system does not have an option to remove it image in Settings, and so we tried to remove it in an unorthodox way.
To disable the connector screen image in Windows 10, without using third-party tools, you should do the following:
Open Registry Editor. (Win + R and in the box you will see enter regedit, and then enter)
Follow the route:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ Windows \ System
There you will have to create a new one price 32-bit DWORD that you will name DisableLogonBackgroundImage.
Set this value to 1.
You will need to restart Window 10 to see if the image appears on the login screen.
The image on the sign-in screen may be reset as soon as you clear the DisableLogonBackgroundImage value and restart your computer.
