lock screen slideshow not working in windows 11

If the lock screen slideshow is not working in Windows 11 while the background picture is functioning, there are a few things you can check:

1. Settings Configuration: Ensure that the lock screen settings are properly configured to use a slideshow. You can do this by going to Settings > Personalization > Lock screen and selecting Slideshow as the background type.
2. Enable Desktop Slideshow Policy: If you are using a managed device, check if the policy to enable the desktop slideshow is set correctly. This can be controlled via Group Policy or MDM settings.
   • For Group Policy, ensure that the policy for enabling the desktop background slideshow is enabled.
   • For MDM, look for the EnableDesktopSlideShowDC and EnableDesktopSlideShowAC policies to ensure they are set to enable the slideshow.
3. Image Source: Make sure that the images you want to use for the slideshow are accessible and in a supported format. If the images are stored on a network drive or external device, ensure that the device is connected.
4. Check for Updates: Sometimes, issues can be resolved by updating Windows to the latest version. Check for any pending updates and install them.
5. Restart the Device: A simple restart can sometimes resolve issues with settings not applying correctly.

If these steps do not resolve the issue, you may want to look into any specific error messages or behaviors that occur when attempting to set the slideshow.

Hello,

Please try this fix. Point the lock screen slideshow to a local folder that is available before sign-in, not to OneDrive online-only files.

Create a folder on this PC, for example Pictures\LockScreenLocal, and copy a few JPG or PNG photos into it so they are truly stored locally. If your images live under OneDrive, make sure they are available offline. In File Explorer check the Status column. If you see a cloud icon on the folder or files, right click them and choose Always keep on this device.

Open Settings. Go to Personalization > Lock screen. Set Personalize your lock screen to Slideshow. Select Add a folder and pick your local folder. Remove any other folders from the list so only that local folder remains.

Optionally turn on Show the lock screen background picture on the sign-in screen if you want the slideshow to appear there too.

Press Win+L to lock and watch for a minute to confirm photos rotate. Tell me what you see. If it still does not start, we will move to the next step.
