允许Windows Store用户手动下载^{(Windows Store)}XAP或APPX文件以进行离线安装的日子已经一去不复返了。随着Microsoft Store的推出，Microsoft停止了该选项。现在，用户只能从商店^(Store)本身安装应用程序。这并不意味着您不能在Windows 10机器上安装APPX文件。但主要是获取APPX 文件^{(APPX file)}。为此，我们将使用一个名为Fiddler的工具。但首先，让我们了解一下什么是APPX文件，什么是Fiddler这安全吗？我们将一一研究所有这些问题。

什么是 APPX 文件

APPX是适用于UWP或通用 Windows 平台^{(Universal Windows Platform)}应用的新文件格式。UWP是Win32应用程序的本机 exe 的替代品。这些应用程序可以利用Windows 10^{(Windows 10)}附带的更安全、功能更强大的API^(APIs)。微软^(Microsoft)推出了Project Centennial，这是一条将Win32应用程序引入UWP平台的途径。这些UWP平台应用目前只能通过Microsoft Store获得。这是一件好事，因为这不会让恶意代码进入您的计算机，因为Microsoft仅允许以应用程序的形式在Microsoft Store^{(Microsoft Store)}中发布干净且非恶意的代码。一些利用Project Centennial并从Win32转换为UWP的应用程序包括Spotify等标题，即将推出的是 iTunes 应用程序。

什么是提琴手

Fiddler是适用于Windows 10的^{(Windows 10)}Win32软件。它具有监视与您的计算机建立的所有HTTP和HTTPS连接的功能。最好的一点是，您不仅可以获取APPX文件^(APPX)的URL ，还可以获取^(URLs)ESD文件以将它们转换为Windows 10更新包。

您可以从此处^(here)的官方下载链接下载最新版本的Fiddler。

安装Fiddler后，请按照此处的步骤操作。

如何从Microsoft Store下载^{(Microsoft Store)}APPX文件

打开提琴手^(Fiddler)。打开后，你会看到一个像这样的窗口。

在顶部的导航栏上，您将看到一个标有 WinConfig 的按钮。 ^{(WinConfig. )}你必须点击它。

单击按钮后，它会询问UAC或用户帐户控制^{(User Account Control)}提示，单击 是后， ^(Yes, )它将打开一个名为 AppContainer Loopback Exemption Utility 的窗口。^{(AppContainer Loopback Exemption Utility.)}

现在，单击“全部免除”。^{(Exempt All. )}然后，单击 保存更改。^{(Save Changes.)}

接下来，在主窗口中，您将看到与 WinConfig 按钮相邻的删除（十字）按钮。^{(remove (cross) button)}

单击^(Click)它，然后您将看到一个下拉菜单，您应该在其中单击Remove all。

您已准备好从Microsoft Store获取您最喜欢的应用程序的^{(Microsoft Store)}APPX文件。

打开Microsoft Store并导航到您喜欢的应用程序的页面并开始下载该应用程序。

现在正在下载应用程序时，导航到仍在后台运行的Fiddler 。由于它在后台运行，它将监视计算机请求和接收的所有流量。

单击同一导航栏上的 Find 按钮并搜索 APPX 并按 Enter 键。

现在，当您执行此操作时，正在下载任何APPX文件的所有连接都将以黄色突出显示，如下图所示。

选择^(Select)任何突出显示的条目并右键单击它。现在将鼠标悬停在复制标签上，然后单击Just URL。

将此URL粘贴到浏览器的地址栏中或将其添加到下载管理器中，以便开始下载APPX文件包。

结论^(Conclusion)

这是一个小技巧，可用于从Microsoft Store获取^{(Microsoft Store)}APPX文件，仅供您个人使用。您不应将此APPX包进一步商业化。但是，对于那些想要在多台机器上部署相同应用程序或带宽低且使用Microsoft Store下载会引发错误的人来说，这可能是一个很好的解决方案。

How to download APPX from Microsoft Store

Gоne are the days when Windows Store users were allowed to download XAP or APPX files manually for offline installations. With the introduction of Microsoft Store, Microsoft discontinued the option. Now, users are only allowed to install applications from the Store itself. This does not mean that you cannot install APPX files on your Windows 10 machine. But the main thing is getting an APPX file. For this, we will be using a tool called Fiddler. But first, let us learn what an APPX file is, What is Fiddler and is this safe? We will be looking at all these questions one by one.

What is an APPX file

APPX is a new file format for UWP or Universal Windows Platform apps. UWP is a replacement for the native exe for Win32 applications. These apps can make use of more secure and more functional APIs that come with Windows 10. Microsoft has introduced Project Centennial, a path for bringing Win32 apps to UWP platform. These UWP platform apps are available only via Microsoft Store at the moment. This is a good thing because this does not let the malicious code get into your computer because Microsoft only allows clean and non-malicious code to be published in the form of apps in the Microsoft Store. Some of the apps that took advantage of Project Centennial and transformed from Win32 to UWP include titles like Spotify and coming soon is the iTunes app.

What is Fiddler

Fiddler is a Win32 software for Windows 10. It has capabilities of monitoring all the HTTP as well as HTTPS connections made with your computer. The best thing about this is that you can not only get URLs for APPX files but also ESD files to convert them into a Windows 10 update package.

You can download the latest version of Fiddler from their official download link here.

After installing Fiddler, follow the steps here.

How to download APPX files from Microsoft Store

Open Fiddler. After it opens, you will see a window like this.

On the navigation bar on the top, you will see a button labeled WinConfig. You will have to click on it.

After you click on the button, it will ask for a UAC or User Account Control prompt, and after clicking Yes, it will open a window named AppContainer Loopback Exemption Utility.

Now, click on Exempt All. And then, click on Save Changes.

Next, in the main window, you will see a remove (cross) button neighboring the WinConfig button.

Click on it and then you will see a drop-down in which you should click on Remove all.

You are all set to get the APPX file of your favorite app from the Microsoft Store.

Open Microsoft Store and navigate to the page of your favorite app and start downloading the app.

While the app is downloading now, navigate to Fiddler which is still running in the background. As it is running in the background, it will be monitoring all the traffic being requested and received by the computer.

Click on the Find button on the same navigation bar and search for APPX and hit Enter key.

Now when you do this, all the connections that are downloading any APPX files will be highlighted in yellow as shown in the image below.

Select any highlighted entry and right-click on it. Now hover over the copy label and click on Just URL.

Paste this URL into your browser’s address bar or add it to your download manager in order to start downloading your APPX file package.

Conclusion

This is a small hack can be used to get the APPX file from the Microsoft Store for your personal use only. You should not further commercialize this APPX package. However, it may be a good solution for those who want to deploy the same app on a variety of machines or for those who have low bandwidth and downloading with Microsoft Store throws an error.
