Unable to set a lock screen background image (Win10).

In case anyone is still looking for a solution, I seem to have found one for 8.1 that seems to have worked on W10 for me over here.

All credits goes to whoever posted the answer to the problem.

Did you have any keys in that location before adding what it mentions? I took a look at mine and I already have all those keys...but they are set for different values. I am hesitant on changing them to what is mentioned.

I only had a couple DWORD ones but none of the ones i had to add. You can always try to backup the entire folder by right clicking the folder and hitting the export function. That way you can use that reg file if anything happens.

This is what worked for me.
I created a temporary second user account, checked that the lock screen personalization was working
then exported this entire key to the root of my drive.

Code:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Lock Screen

I then went back to my original profile, deleted the same key above and imported the .reg file that I saved.
After that my images returned & I was able to change the lock screen and see the spotlight picture.

I did same things but It didn't work.
I created new user and the lock screen personalizations was working, but I exported the .REG and imported it and it didn't work.

Code:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Lock Screen

I simply change one registry value -
Run/regedit/HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Personalization
right click NoLockScreen/Modify and set value data from 1 to 0/OK. Re-open Settings/Personalization. Done !
regedit screen and Lock Screen personalization screen before (grayed out) and after I reset value to 0 (I could choose and browse)

I tried all of things and I think it's so strange because I can't choose pictures because it does not apear in the screen.



If I try to put manual a picture the system stop and I can't see any picture in my screen.



It's so strange .....

I tried many different things with the registry entries including creating a new user and using those. Also tried what wpmartins2803 mentioned...that value did not exist, but I added to try it anyway. Still no luck. I did somewhere along the line get the preview to load when I selected an image via browse, but it still did not function fully and no image in the "Choose your picture" part.

I tried the solution above, and it worked perfectly.
