Change Windows Background Wallpaper as Lock Screen

Question

I have Windows 10 laptop and I really like all the Lock Screen wallpapers that Windows change automatically occasionally. Is it possible to change the my desktop background with the same wallpaper at the same time?

Save the following as a Powershell script:

$files = gci $Env:LocalAppData\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets | where Length -gt 1kb

if ($files) {
    $shell = New-Object -ComObject Shell.Application
    #destination for pictures (if doesn't exist, will be created)
    $folder = "$Env:USERPROFILE\OneDrive\Pictures\Wallpaper\Spotlight"
    if (!(Test-Path $folder)) { mkdir $folder }
    $files | % {
        $_ | Copy-Item -Destination $folder\$_.jpg
        Get-Item $folder\$_.jpg
    } | % {
        $namespace = $shell.namespace($folder)
        $item = $namespace.ParseName($_.Name)
        $size = $namespace.GetDetailsOf($item, 31)
        if ($size -match '(\d+) x (\d+)') {
            $width = [int]($Matches[1])
            $height = [int]($Matches[2])
        }
        if (!$size -or $width -lt 1920 -or $height -lt 500) {
            Remove-Item $_
        }
    }
}

If you wish, modify the line $folder = "$Env:USERPROFILE\OneDrive\Pictures\Wallpaper\Spotlight" to place the files where you want them.

Save the following as an .xml file:

<?xml version="1.0" encoding="UTF-16"?>

      <Arguments>-ExecutionPolicy Bypass -file "C:\Path\To\PowerShel\Script\savespotlight.ps1"</Arguments>
    </Exec>
  </Actions>
</Task>

If you modified the PowerShell script, you'll need to make matching change in the XML file. Also, you'll need to change the Arguments line to point to your Powershell script file location: <Arguments>-ExecutionPolicy Bypass -file "C:\Path\To\PowerShel\Script\savespotlight.ps1"</Arguments>

Open the Task Scheduler and import this XML as a scheduled task. Make any adjustments to the settings that you wish. Set the trigger to run this script daily.

Now open Settings > Personalize and set your Background to a Slideshow and select the folder you've specified as the source folder for the slideshow images.
