Unlike the lock screen wallpaper which is highly customizable, the sign-in screen wallpaper (also known as the hero desktop image) of Windows 10 is standard for everyone. This guide describes two simple methods to remove the hero desktop image and replace it with a solid color background.
The Threshold2 update introduced a new setting to toggle Windows 10's default hero desktop image on/off.
Click Start > Settings and then navigate to Personalization > Lock screen. Toggle the Show Windows background picture on the sign-in screen option Off:
With The Registry Editor
Right-click on the Start menu and select the Run command. Type the
regedit
command and press Enter to open the Registry Editor.
Next, go to HKEY_LOCAL_MACHINE>SOFTWARE>Policies>Microsoft>Windows>System and then create a new Dword (32 bit) Value, which you'll name DisableLogonBackgroundImage:
Set its value to 1 and click on OK to validate:
Close the Registry Editor and reboot your PC to apply your new settings.
N.B. You can restore your default settings by deleting the DisableLogonBackgroundImage key in the registry.
How To Change the Color of the Sign-In Screen
Click on Start > Settings > Personalization > Colors. Toggle the switch below Automatically pick an accent color for my background to the Off position and choose the accent color you'd like to use:
Windows 10 will apply the new color scheme system-wide, including on the sign-in screen.
