用PowerShell保存Windows聚焦图片的方法

win10的锁屏聚焦很多图片非常不错，就是不能保存，这个方法只需一段代码就能保存
先复制文末的代码，复制，再打开Win10自带的Windows PowerShell，粘贴到里面回车即可保存
保存的目录会在Windows PowerShell里面显示，就是此电脑>图片>Spotlight>Horizontal

add-type -AssemblyName System.Drawing
New-Item "$($env:USERPROFILE)\Pictures\Spotlight" -ItemType directory -Force;
New-Item "$($env:USERPROFILE)\Pictures\Spotlight\CopyAssets" -ItemType directory -Force;
New-Item "$($env:USERPROFILE)\Pictures\Spotlight\Horizontal" -ItemType directory -Force;
New-Item "$($env:USERPROFILE)\Pictures\Spotlight\Vertical" -ItemType directory -Force;
foreach($file in (Get-Item "$($env:LOCALAPPDATA)\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets\*"))
{
    if ((Get-Item $file).length -lt 100kb) { continue }
    Copy-Item $file.FullName "$($env:USERPROFILE)\Pictures\Spotlight\CopyAssets\$($file.Name).jpg";
}

foreach($newfile in (Get-Item "$($env:USERPROFILE)\Pictures\Spotlight\CopyAssets\*"))
{
    $image = New-Object -comObject WIA.ImageFile;
    $image.LoadFile($newfile.FullName);
    if($image.Width.ToString() -eq "1920"){ Move-Item $newfile.FullName "$($env:USERPROFILE)\Pictures\Spotlight\Horizontal" -Force;}
    elseif($image.Width.ToString() -eq "1080"){ Move-Item $newfile.FullName "$($env:USERPROFILE)\Pictures\Spotlight\Vertical" -Force; }
