将以下内容保存为 Powershell 脚本：

$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 $_
        }
    }
}

如果愿意，请修改该行$folder = "$Env:USERPROFILE\OneDrive\Pictures\Wallpaper\Spotlight"以将文件放置在所需的位置。

将以下内容保存为 .xml 文件：

如果您修改了 PowerShell 脚本，则需要在 XML 文件中做出相应的更改。此外，您还需要更改参数行以指向您的 Powershell 脚本文件位置：<Arguments>-ExecutionPolicy Bypass -file "C:\Path\To\PowerShel\Script\savespotlight.ps1"</Arguments>

打开任务计划程序并将此 XML 导入为计划任务。根据需要调整设置。设置触发器以每天运行此脚本。

现在打开设置>个性化并将背景设置为幻灯片，并选择您指定为幻灯片图像的源文件夹的文件夹。
