This service handles background tasks like delivering lock screen wallpapers, system suggestions, and promotional app recommendations.

How to Fix ContentDeliveryManager.background.dll Errors (Without Downloading)

Do not download this DLL file from third-party websites. Those files often contain malware. Instead, fix the error natively using built-in Windows tools.

1. Run the SFC and DISM Commands

Windows can automatically find and replace missing or corrupted system files from its own secure local cache.

Press the Windows Key.
Type cmd.
Right-click Command Prompt and select Run as administrator.
Type DISM.exe /Online /Cleanup-image /Restorehealth and press Enter.
Wait for the process to finish.
Type sfc /scannow and press Enter.
Restart your computer after the scan completes.

2. Re-register the Windows Content Delivery Manager

If the file is present but Windows cannot read it properly, you can re-register the package using PowerShell.

Right-click the Start Menu button.
Select Terminal (Admin) or Windows PowerShell (Admin).

Paste the following command and press Enter:

Get-AppxPackage -AllUsers Microsoft.Windows.ContentDeliveryManager | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($ .InstallLocation)\AppXManifest.xml"}

Restart your system.

3. Reset Windows Spotlight Settings

If the error occurs specifically during startup or when locking your screen, resetting the Spotlight configuration files will fix it.

Open Settings (Windows Key + I).
Go to Personalization > Lock screen.
Change the background from "Windows Spotlight" to Picture or Slideshow.

Press Windows Key + R, paste the following path, and press Enter:

%USERPROFILE%\AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager cw5n1h2txyewy\Settings

Delete all files inside this folder (roaming.lock and settings.dat).
Go back to your Lock screen settings and change the background back to Windows Spotlight.
