For the
solution, scroll down, for the story, read on.
After
returning from holiday last week I had some Windows Updates to install and
afterwards my lock screen was changed. Whenever I locked my computer it would
show up like below.
 |
| Black Lock screen without background |
And when
I then want to log in and entered the sign-in screen, the Windows spotlight
background appears, as I expected in the previous screen.
 |
| Sign-in screen with background |
After
some searching I couldn't find this specific issue so I started looking at the
Lock screen options myself.
You can
open the Lock screen options by typing "lock" after pushing the start
button and clicking Lock screen settings,
or opening the Action Center by clicking
on the notification icon and clicking All settings > Personalization > Lock screen.

| Action center |
Either
way you should end up in this screen:

| Lock screen settings |
I found
out that the slider on the bottom, the one that reads "Show lock screen
background picture on the sign-in screen", is the culprit. Apparently this
also makes the background go away at the lock screen, they could've mentioned
that IMO…
TL;DR
By
switching the button in the Lock screen settings to Off, the background will appear again in the lock
screen.
