Windows 10: Can't change lock screen background image.

changing the background images

Hi,

In order to help you better, could you please confirm a couple of things.

I suggest you to follow the below steps to change the background picture and check if it helps.

• In the search type as ‘Settings’ and click on it.
• Select ‘Personalization’, under ‘Background’ option select as ‘Picture’.
• Under ‘Choose your picture’ select any picture accordingly or you can browse the picture from your computer.

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?).
