    Hi, I'm Henry! I will help you with this.

    It looks like you're encountering AppReadiness error event 10 in Windows Server 2025, specifically related to the Microsoft.Windows.ContentDeliveryManager package. This error occurs when Windows fails to register the package due to missing or improperly localized resources.

    1. Reinstall System Apps via PowerShell
    • Open PowerShell as Administrator and run the following command to re-register all system apps: Get-AppxPackage -allusers | foreach {Add-AppxPackage -register "$($_.InstallLocation)\appxmanifest.xml" -DisableDevelopmentMode}
    • This may resolve missing resource issues.
    1. Manually Remove & Reinstall the Problematic Package
    • Open PowerShell as Administrator and run: Get-AppxPackage *ContentDeliveryManager* | Remove-AppxPackage
    • Then reinstall it using: Add-AppxPackage -register "C:\Windows\SystemApps\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\AppxManifest.xml" -DisableDevelopmentMode
    1. Check Event Viewer for Additional Errors
    • Open Event Viewer (eventvwr.msc) and look for related errors under Application and System logs.
    1. Perform a System File Check & Repair
    • Run the following commands in Command Prompt (Admin):
    • sfc /scannow
    • DISM.exe /Online /Cleanup-image /Restorehealth

    Let me know if any of these solutions work for you
