Blank Lockscreen Image Windows 10 1709

Another strange one today. After upgrading a PC to Windows 10 1709 build 16299 we found that our lockscreen image that had been set via GPO for over 2 years, was no longer showing. It was simply showing a blank assent colour.

After some aggressive Googling i came across someone who had sussed it was to do with a registry key that many of us set many moons ago, when the first versions of Windows 10 were released.


To rectify the issue we need to update the registry key that we set. It was called DisableLogonBackgroundImage and was used to remove the old type of lockscreen overlay, called the "hero" wallpaper.

NOTE -  If you are setting this globally, please be aware that this registry key was NEEDED for Windows 10 version 1511, so may revert 


DisableLogonBackgroundImage = DWORD 0

0 (enable) 
1 (disable)

As always you can either manually change this, or us GPP to deploy it globally.

We then simply set the key back from 1 to a zero. Voila quick reboot and it works.
