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 (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%MicrosoftWindowsSystemData 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.
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 .
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.
