Welcome Nickson Onsongo,
Thanks for reaching out to Microsoft Q&A Forum. I understand Windows Spotlight is working for your desktop background but not on the lock screen, and the issue has persisted despite trying multiple fixes.
Please make sure you already tried the Q&A Assist steps. In addition, please try the following.
Before proceeding, could you please confirm:
- Which Windows 11 version are you running (23H2, 24H2, or later)?
- Does the lock screen show a static image, a black screen, or the default Windows image when Windows Spotlight is selected?
In the meantime, you can try these steps:
Option 1: Re-register Windows Spotlight
- Open Windows Terminal (Admin).
- Run:
Get-AppxPackage -allusers Microsoft.Windows.ContentDeliveryManager | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"} - Restart the PC.
Option 2: Clear the Spotlight cache
- Press Win + R and enter:
%LocalAppData%\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState - Open both the Assets and Settings folders.
- Delete the contents of both folders.
- Restart the PC and enable Windows Spotlight again.
Option 3: Repair system files
- Open Command Prompt as Administrator
- Run:
DISM /Online /Cleanup-Image /RestoreHealth - After it completes, run:
sfc /scannow - Restart the PC
