如果您使用的是Windows 10，您可能已经注意到锁定屏幕(lock screen)通常会显示一个非常漂亮的背景图像(background image)，该图像是从Bing中自动选择并自动调整为适合您的桌面屏幕(desktop screen)大小的。如果您有高分辨率显示器(high-resolution monitor)，该功能尤其适用。
在 4K 或WQHD (2560×1440) 显示器上，高分辨率图像看起来非常棒。该功能称为Windows Spotlight ，它是(Windows Spotlight)Windows 10 锁定屏幕(Lock Screen)设置对话框中的一个选项。
唯一的问题是没有简单或快速的方法将图像下载到您的计算机。也没有任何方法可以将Windows Spotlight 功能(Windows Spotlight feature)用于桌面墙纸(desktop wallpaper)。您可以从幻灯片(Slideshow)中进行选择，但它需要您指向一个包含图片的文件夹。
在本文中，我将向您展示如何将这些图片从Windows Spotlight获取到您的计算机上，然后您可以将其提供给桌面墙纸的(desktop wallpaper)幻灯片选项(slideshow option)。
如果您不确定Windows Spotlight是什么，或者您的计算机上是否未启用它，您可以单击开始并输入(start and type)锁定屏幕( lock screen)以显示此对话框。
如您所见，锁屏(lock screen)图像非常漂亮，大约每两天更换一次。幸运的是，您计算机上显示的所有图像实际上都已存储在您的系统中，尽管不是以非常用户友好的方式。
查找 Windows 聚光灯图像
第一步是在您的Windows 10系统上找到所有存储的图像。为此，您需要打开Windows 资源管理器并单击(Windows Explorer and click)“查看”(View)选项卡。
继续检查文件扩展名( File name extensions)和隐藏项目(Hidden items)框。完成此操作后，使用您自己的用户帐户(user account)代替用户名导航到下面的以下目录。
C:\Users\用户名\AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets
如果您已经使用Windows Spotlight(Windows Spotlight)一段时间，您应该会在此文件夹中看到一堆文件。继续并单击“大小(Size)”列以按文件大小(file size)对项目进行排序。
我提到按大小排序的原因是因为文件夹中的某些文件小于 50 KB，并且不是壁纸图像。您可以忽略这些文件。现在您要做的是在驱动器的其他位置创建一个新文件夹，用于存放墙纸图像。
选择(Select)所有大于 100KB 左右的文件并将它们复制到新文件夹中。要复制，请选择文件，然后按住右键单击并将图像拖动到第二个资源管理器窗口(Explorer window)。
您会注意到它会显示“移动(Move)到壁纸”，您可以忽略它，因为您按住鼠标右键单击按钮。但是，当您放手时，您会看到另一个对话框，说这些文件可能会损害您的计算机。
您显然可以忽略这一点，因为这些文件已经在您的计算机上。出现该消息的原因是因为它们正在从受系统保护的隐藏文件夹中移动。单击“确定(Click OK)” ，然后您将能够选择“在此处复制”(Copy here)。
要使图像再次可见，您必须右键单击它们以重命名它们。由于您不知道照片会是什么，所以只需给它一个数字作为名称。您还必须添加文件扩展名(file extension)。图像都将是 .PNG 或 .JPG，因此请按此顺序尝试。
重命名文件后，继续并双击它以查看它是否在您的默认照片查看器程序(default photo viewer program)中打开。如果是这样，你就可以走了。如果没有，请尝试其他文件扩展名(file extension)。当您重命名它们时，您应该开始在资源管理器(Explorer)中看到图像的预览。有些保留了默认的图像占位符图标(default image placeholder icon)，但图像加载得很好。
这就是它的全部内容。无论如何，这不是最简单的程序，但它没有风险，而且相当简单。我建议打开Spotlight几个星期，然后抓取所有图像。这里唯一的缺点是文件夹内容经常更改，并且它不会记录曾经显示的每张图像。它会删除一些并用更新的图像替换它们，因此您可能必须每隔几个月重复此过程。
其他获取 Spotlight 图像的方法
如果您觉得这些图像的工作量太大，您还有其他几个选择。首先(First)，您可以花一美元购买 SpotBright 应用程序(SpotBright app)，只需单击两下即可下载Spotlight图像。
第二种方法更简单。有人很好地找到了Spotlight中使用的每张图片并将其发布到Imgur。这张专辑中至少有200+ images in this album，它们都是全高清分辨率(HD resolution)的图片。使用该站点，您可以下载比隐藏文件夹中更多的Spotlight图像。(Spotlight)
第三种方法是使用巧妙的PowerShell 命令(PowerShell command)。即使您不是技术人员，它也很容易运行，并且可以为您节省大量的手动工作。只需(Just)在桌面上创建一个名为Pics的文件夹，然后单击Start 并键入(Start and typing)powershell打开PowerShell。
现在只需将以下命令复制并粘贴(copy and paste)到PowerShell 窗口中，然后按 Enter(PowerShell window and press Enter)：
Get-ChildItem -Path $env:localappdata\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets | Copy-Item -dest {"$home\desktop\pics\" + $_.BaseName + ($i++) +".jpg" }
打开桌面上的Pics文件夹，瞧(desktop and voila)！LocalState/Assets文件夹中的所有图像都应该在那里。您需要删除无用的文件，否则可以节省大量时间。享受！
How to Download Windows 10 Spotlight/Lock Screen Images
If you’re using Windowѕ 10, you’vе probably noticed that the lock screen usually displays a really nice background image that iѕ automatically chosen from Bing and autоmatically ѕized for your desktop screen. If you have a high-rеsolυtion monitor, the feature works especially well.
On a 4K or WQHD (2560×1440) monitor, the high-resolution images look absolutely great. The feature is called Windows Spotlight and it’s an option in the Windows 10 Lock Screen settings dialog.
The only problem is that there is no easy or quick way to download the images to your computer. Nor is there any way to use the Windows Spotlight feature for your desktop wallpaper. You can choose from Slideshow, but it requires you to point to a folder with pictures.
In this article, I’ll show you how to get those pictures from Windows Spotlight onto your computer, which you can then feed to the slideshow option for your desktop wallpaper.
If you’re not sure what Windows Spotlight is or if it’s not enabled on your computer, you can click on start and type in lock screen to bring up this dialog.
As you can see, the lock screen images are really nice and change about every two days. Luckily, all of the images that have been shown on your computer are actually already stored on your system, albeit not in a very user-friendly way.
Find Windows Spotlight Images
The first step is to find all the stored images on your Windows 10 system. To do this, you’ll need to open Windows Explorer and click on the View tab.
Go ahead and check both the File name extensions and Hidden items boxes. Once you have done this, navigate to the following directory below, using your own user account in place of username.
C:\Users\username\AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets
You should see a bunch of files in this folder if you have been using Windows Spotlight for some time. Go ahead and click on the Size column to order the items by file size.
The reason I mention sorting by size is because some of the files in the folder are less than 50 KB and are not the wallpaper images. You can just ignore those files. Now what you want to do is create a new folder somewhere else on your drive that you will use for the wallpaper images.
Select all the files that are larger than 100KB or so and copy them to the new folder. To copy, select the files and then hold right-click and drag the images to the second Explorer window.
You’ll notice that it’ll say “Move to Wallpapers”, which you can ignore since you’re holding down the right-click button your mouse. When you let go, you’ll get another dialog, however, saying the files can harm your computer.
You obviously can ignore this since these are files that are already on your computer. The reason why the message appears is because they are being moved from a system protected hidden folder. Click OK and then you’ll be able to choose Copy here.
To make the images viewable again, you have to right-click on them to rename them. Since you have no idea what the photo will be, just give it a number for the name. You’ll also have to add the file extension. The images are all going to be either .PNG or .JPG, so try them in that order.
Once you rename the file, go ahead and double-click on it to see if it opens in your default photo viewer program. If it does, you’re good to go. If not, try the other file extension. You should start seeing previews of the images in Explorer also as you rename them. Some remain with the default image placeholder icon, but the images load just fine.
That’s about all there is to it. It’s not the simplest procedure by any means, but it’s not risky and it’s fairly straight-forward. I suggest turning on Spotlight for a couple of weeks and then grabbing all the images. The only downside here is that the folder contents change often and it doesn’t keep a record of every single image ever shown. It will delete some and replace them with newer images, so you might have to repeat this procedure every couple of months.
Other Ways to Get Spotlight Images
If you feel that’s way too much work for those images, you do have a couple of other choices. First, you can spend a dollar and get the SpotBright app, which allows you to download the Spotlight images in just two clicks.
The second way is even easier. Someone has been nice enough to find each image used in Spotlight and post it to Imgur. There are at least 200+ images in this album and they are all full HD resolution images. Using the site, you have the advantage of downloading a lot more of the Spotlight images than you’ll find in the hidden folder.
A third way is to use a clever PowerShell command. Even if you are non-technical, it’s very easy to run and it’ll save you a lot of manual work. Just create a folder on your desktop called Pics and then open PowerShell by clicking on Start and typing in powershell.
Now just copy and paste the following command into the PowerShell window and press Enter:
Get-ChildItem -Path $env:localappdata\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets | Copy-Item -dest {"$home\desktop\pics\" + $_.BaseName + ($i++) +".jpg" }
Open the Pics folder on your desktop and voila! All the images from the LocalState/Assets folder should be there. You’ll need to delete out the useless files, but otherwise it saves you a lot of time. Enjoy!
