Windows 10: Enabling the "show background image on sign-in" sets a grey background on my lock screen

As the title says. I've tried many workarounds that have been posted, powershell etc. but none worked.

Here is an image.

Can't set background picture on sign-in screen


Hello Rob, *Smile

Odd. Just to verify, did you scroll down all the way on the Lock Screen settings page?

If this setting is missing, then you may have disabled the sign in screen background. Enabling it should restore this setting if this is the case.

Lock screen background image does not appear (Anniversary Update)


Hi folks,

Background

• A year or more ago I followed [this guide](How to Change the Login Screen Background on Windows 10) to set the Sign-in screen to a single colour rather than having to use Microsoft's default background image.
• So I set my own custom background image for the Lock screen (with no problem), and then once I hit a key to bring up the Sign-in screen it would should a solid background colour (happy days!).

Issue

• I just upgraded to the Anniversary Update with no problems. My setup of Lock screen = custom image and Sign-in screen = solid colour was still working.
• I read that Microsoft had changed it so that when you hit a key to bring up the Sign-in screen it would just keep your Lock screen image behind and show the password box on top. This sounded good to me so I ran the 'undo' script provided in the link above (the 'enable' script).
• Now, when I lock my computer I see no image at all (a completely black background, but it's not broken because the date and time show up), and only when I hit a key to bring up the Sign-in screen do I see the custom Lock screen background image I selected. *Sad
• The kicker is: if I go into the Lock screen settings and turn "Show lock screen background picture on the sign-in screen" OFF, then it reverts to my old custom setup: showing my selected Lock screen background image on the lock screen, but then showing a solid colour when I bring up the Sign-in screen :/

I'm wondering if the registry setting changed at all for the Anniversary Update? I note that in the article and in the registry script they refer to it as "login/logon" whereas the setting in the Anniversary Update references "sign-in". Don't know if there's a clue there or it's just a red herring?

Can anyone help me get back to the default Anniversary Update behaviour (Lock screen background image shows on lock screen and sign-in screen)?

UPDATE: Interestingly, when I do a restart, the default Anniversary Update behaviour works. Ie. it shows the background image on the first screen and also on the sign-in screen (is there a subtle difference between the first screen you see after powering up vs any subsequent lock screen?).
