There is a topic for this here that asks about removing the screen: How to completely disable welcome screen on Windows 10 Anniversary?
However, that was for Windows 10-Anniversary and there was no resolution in that topic. Also, they wanted to completely remove the screen.
I am requesting information on removing the screen (in case there has been a solution since the initial topic or since the release of Creators), but am also open to removing assets on the screen. Removing the user set picture, name, and loading circle with the "Welcome" message. This way I can just set a custom background picture and that should be enough. Any help is greatly appreciated.
