Windows 10: Unable to set a lock screen background image (Win10).

I am currently unable to set a lock screen background image (Windows 10 Pro 64-bit). When on the Lock Screen customization window, it is pretty bare with no images to choose from. Browsing and choosing any image results in nothing happening and it does not add it (refer to LockScreen image attached). If I try to set it when viewing any image it has the error "Can't set as lock screen. Make sure the file isn't damaged and try again." (refer to PhotoSet image attached). Also note that the Slideshow option is not in the dropdown either.

Some background on this is probably needed, so here's what has happened/been done:
In Windows 8.1 I customized the default lock screen to a custom image using the guide at http://www.eightforums.com/tutorials...ndows-8-a.html (the manual method/Option 2). Yesterday I upgraded to Windows 10 and it set the lock screen to a basic color. Then the fun started...

1. Lock Screen customization appeared normal/functional. Tried choosing a different image or custom image. It would appear set, but lock screen would not change (even after reboot).

2. Tried troubleshooting by taking the same actions as in Windows 8.1. Did the same actions for the new folders that Windows 10 uses in the %ProgramData%\Microsoft\Windows\SystemData\ folder (deleted the images within the lettered folder(s)).

3. Checked every Registry Key I found mention of when searching online (none needing to be changed).

4. I renamed the SystemData folder as a website recommended. Windows did make a new, fresh copy. However this is what kicked it over to the state I am in now. Restoring the old folder did no good.

5. Before coming here I did one last thing. I ran sfc /scannow. It claimed the img100 was corrupt and replaced it, but nothing changed.

Anyone have any idea what I can do to restore the functionality of the Lock Screen customization without reinstalling Windows? Note that I am not trying to change the logon screen background...even though I would love to do that too. Other than this issue everything is running great/perfect.

Can't change lock screen Win 10 after delete task schedule

Cannot change log-in screen backgound in Windows 10

I have a custom photo as my lock screen background. I've found instructions that indicate that the lock screen background can also be set as the log-in screen background by going to settings-personalization-lock screen and then page down and there is an
option to set the log-in screen to the lock screen background. However, I have no such option in my personalization-lock screen settings. My only option is to either turn on or turn off "show Windows background picture on sign-on screen". There is no option
for anything other than to either turn on or off the Windows background picture - no option to set the log-in (sign-in) screen to any other image.

I've been unable to find any solution to this issue. Any suggestions are much appreciated.

Thanks.

 

You're not alone. I'm experiencing EXACTLY the same problem.

 

check if the secure logon option is enabled

windows key+R

type secpol.msc





open local policies>security options>interactive logon:do not require CTRL + ALT + DEL

and set it to "enabled"

 

I always have mine set to require Ctrl+Alt+Del, but I went ahead and tried turning that off (Enabling the option) like you mentioned. The only change I saw was instead of a basic purple color it is now black. Sadly, trying to set the lock screen background still has the same issues after doing this. Thank you for the suggestion though *Smile.

 

I am having the exact same issue.






I hope someone comes up with a fix.

 

I've also seen the issue "Can't set as lock screen". The work around for me, was to open up the Photos app directly and then find the photo within the app. If I just clicked on the actual photo first, I also get the error.

 

My wife's computer had the problem in the personalization screen. No matter what I tried, I couldn't set a lock screen image. I screen for a reg key that could be locking the image and found this location. There was a key with a locked image, must have been there in Win8.1 before the upgrade. Deleting the reg key for the image fixed my issue.

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization

 

That did not work.

 

I don't have this key

 

Tried opening the Photos App first. It doesn't error doing it that way, but the lock screen doesn't actually change. Lock screen customization screen still blank.

I don't have the registry key either.

 

Hi, I have the same problem. I tried everything in this post and other found on internet but I didn't fix it. I have Windows 10 Home and I don't have Policy Group Editor.

 

Ive just re installed win10 to test.

I was able to change the lock screen, and it showed up correctly, Prior to joining my domain.

Domain controller is a windows server 2012 box.

have made no other changes to the pc other than joining the domain.

now I only get a solid blue background on the lock screen.

 

Further notes for reference: I am not on a domain. I am the only user (and admin) on my PC. No group policies and such set.
