Windows 10: Changing Boot & Logon Screens

I'm making a theme for myself & have a few questions:
1. How do I change the Windows 10 Boot Screen & can I have it show a different image each time?
2. How do I change the Windows 10 Logon/Lock Screen & can I have it show a different image each time?

[SOLVED] Changing the wallpaper on the BOOT, LOCK, and LOGON screens

I did.





Didn't make a difference!

 

[SOLVED] Changing the wallpaper on the BOOT, LOCK, and LOGON screens

I am on 1803. I use Picture under Background and NOT Windows spotlight.





I didn't encounter the default wallpaper issue when I was warm booting. Try the HeatherS1969 approach carefully step-by-step.

 

[SOLVED] Changing the wallpaper on the BOOT, LOCK, and LOGON screens

Okay, it's like this.

My system had been showing the default Win 10 landscape wallpapers in all screens. Just recently, I decided to change them. I used Settings -> Personalization -> Lock Screen to replace the wallpaper using my own picture collection and set the same wallpaper for log-in (LOGON) screen. I manually locked my system to test it, no problem. When my system timed out, no problem. The new custom wallpaper was shown on both LOCK and LOGON screens. I thought that was it.

Then, every time I cold-booted, the system began showing the default Win 10 landscape wallpaper again. If I touched the mouse or keyboard, the LOGON screen popped up with the new custom wallpaper. From this point on until shutdown, if the system got locked manually or timed out, the new custom wallpaper was shown on the LOCK and LOGON screens all the time. If I shutdown the system and cold-booted, the default Win 10 landscape wallpaper came up again on (what I call) the BOOT screen. I repeated the Settings procedure many times, but it did not produce the result I wanted. I thought the picture or setting was stuck or it was a bug unique to my system/setup.

When I began looking for a solution on-line, I discovered my case was happening to others, too. Almost all of the solutions offered were about the same procedure mentioned above until I came across that of HeatherS1969. Because the last step ended on the Lock Screen settings page, I thought at first that the HeatherS1969 approach simply used a different starting point but was ultimately the same, but the follow-up by MichelleBryant-Thomas in the thread suggested that it worked. So, I carefully repeated the steps as instructed, and it fixed the issue.

Usual procedure:
Settings -> Personalization -> Lock Screen to replace the background picture

The HeatherS1969 approach:
Start -> click on account picture -> change account settings -> Sign-in options -> Related settings / Lock screen -> Lock Screen to replace the background picture

I use Classic Shell, so I'm not sure if the steps are the same for people who use the default Win 10 (Metro?) setup. In both procedures, one ends up on the Lock Screen settings page, but choice made through the HeatherS1969 approach actually changes the BOOT screen wallpaper.

I hope that clears things up for you.
