Restart your PC and check if the issue still persists.

Hi,

There is no option to allow sub-folders, however they aren't in a sub-folder.

I don't believe that any of them are DRM-protected. Some are screenshots from games I have played. They were in a folder on my desktop, and I do not use onedrive.

The images are either .jpeg or .png

I tried setting up a new file in the following filepath: C:\Users\Wallpaper2 but this also did not work.

Thank you

Thanks for checking.

1. Are the images in a subfolder?

If yes, make sure “Include subfolders” is enabled when choosing the slideshow folder.

2. Are the images DRM-protected or in a sync folder like OneDrive?

Move them to a local folder like C:\Pictures\LockscreenSlideshow.

3. What is the image format?

Make sure all files in the folder are valid .jpg or .png.

Meanwhile , Try below steps

1: Set Up a Clean Folder

a. Create a new folder, e.g.,

C:\Users<YourName>\Pictures\LockscreenSlides

b. Copy only clean .jpg or .png files into it , try 3 - 5 images first.

c. Make sure the folder has read permissions for all users.

2: Configure Lock Screen Properly

a. Open Settings > Personalization > Lock screen

b. Set Background to Slideshow

c. Click Browse, choose the new folder

d. Turn ON:

Include Camera Roll folders from this PC and OneDrive (if using Camera Roll)

Let slideshow run even if battery saver is on

3. Try another regsitry editor.

a. Press Win + R > type regedit > Enter

b. Go to:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization

c. If "Personalization" doesn’t exist, right-click > New > Key > name it Personalization

d. In that key:

Right-click > New > DWORD (32-bit) Value

Name: NoLockScreenSlideshow

Set value to 0

Close Registry Editor

e. Restart

Hi,

I tried both of those and neither of them worked.

When I went into regedit i went to the setting and it was already set to 1, so I changed it to 0 and back to 1.

Thanks
