I'm glad it could help.
So I read this thread and the link. Like someone mentioned the link says that by now windows should have merged the lock screen and the start up screen. Mine isn't merged. I have been able to confirm this because when I tried to change the start up screen by changing the "lock screen" in settings it changed it to a different stock photo and is stuck as such yet when I hit win+L it shows the lock screen and the picture I set. Seeing as I'm on a PC I never use and in fact never before seen the lock screen until testing this. I would really like to know how to change the start up screen. I know this is an old thread but this is driving me crazy to the point that I made an account here just to see if my necromancy could conjure up an answer from the level 90 Windows Pros
Edit - I fixed it! Just in case this helps anyone this is what worked. First off I tried everything I could find on this forum about it. The file that I wanted to set was on my D drive. I copied it to a new directory on C opened it and used the photo program to "set as lock screen" then I re selected "show lock screen background picture on the sign in screen". I'm not sure if it was the movement from D to C or that I used the photo program to set it instead of browsing in the settings screen but it worked. Strange.
