Package desktop applications (Desktop Bridge)

Take your existing desktop application and add modern experiences for Windows 10 users. Then, achieve greater reach across international markets by distributing it through the Microsoft Store. You can monetize your application in much simpler ways by leveraging features built right into the store. Of course, you don't have to use the store. Feel free to use your existing channels.

Desktop Bridge

When you create a package for your desktop application, your application will get an identity and with that identity, your desktop application has access to Windows Universal Platform (UWP) APIs. You can use them to light up modern and engaging experiences such as live tiles and notifications. Use simple conditional compilation and runtime checks to run UWP code only when your application runs on Windows 10.

Aside from the code that you use to light up Windows 10 experiences, your application remains unchanged and you can continue to distribute it to your existing Windows 7, Windows Vista, or Windows XP user base. On Windows 10, your application continues to run in full-trust user mode just like it’s doing today.


The ability to create a Windows app package for your desktop application (otherwise known as the Desktop Bridge) was introduced in Windows 10, version 1607, and it can only be used in projects that target Windows 10 Anniversary Update (10.0; Build 14393) or a later release in Visual Studio.


Checkout this series of short videos published by the Microsoft Virtual Academy. These videos walk you through the entire process of bringing your desktop application to the Universal Windows Platform (UWP).


Here's some reasons to create a Windows App package for your desktop application:

✔️ Streamlined deployment. Apps and games that use the bridge have a great deployment experience. This experience ensures that users can confidently install an application and update it. If a user chooses to uninstall the app, it's removed completely with no trace left behind. This reduces time authoring setup experiences and keeping users up-to-date.

✔️ Automatic updates and licensing. Your application can participate in the Microsoft Store's built-in licensing and automatic update facilities. Automatic update is a highly reliable and efficient mechanism, because only the changed parts of files are downloaded.

✔️ Increased reach and simplified monetization. Choosing to distribute through the Microsoft Store expands your reach to millions of Windows 10 users, who can acquire apps, games and in-app purchases with local payment options.

✔️ Add UWP features. At your own pace, you can add UWP features to your app's package, like a XAML user-interface, live tile updates, UWP background tasks, app services, and many more.

✔️ Broadened use-cases across device. Using the bridge, you can gradually migrate your code to the Universal Windows Platform to reach every Windows 10 device, including phones, Xbox One and HoloLens.

First, prepare your application by reviewing the article Prepare to package your desktop app, and then addressing any of the issues that apply to your application before you create a Windows app package for it. You might not have to make many changes to your application before you create the package. However, there are some situations that might require you to tweak your application before you create a package for it.


There are several different ways to create an MSIX package for your desktop app.

Build an MSIX from an existing app package

If you already have an app package (for example, an MSI or App-V Installer), we recommend that you use the MSIX Packaging Tool to repackage your existing desktop app to the MSIX format. It offers both an interactive UI and a command line for conversions, and gives you the ability to convert an application without having the source code.


An earlier tool named the Desktop App Converter is also still available for repackaging an existing desktop app package to the MSIX format. However, this tool is now deprecated, and we recommend that you use the MSIX Packaging Tool instead.

Build an MSIX from source code using Visual Studio

If you maintain your application by using Visual Studio, and your application doesn't have an installer or your installer doesn't perform too many complicated tasks, consider using Visual Studio instead.

Visual Studio makes it abundantly easy to create a package. You'll add a packaging project, reference your desktop project, and then press F5 to debug your app. No manual tweaks necessary. This new streamlined experience is a vast improvement over the experience that was available in the previous version of Visual Studio. Here's a few other things you can do with it.

✔️ Automatically generate visual assets.

✔️ Make changes to your manifest by using a visual designer.

✔️ Generate your package by using a wizard.

✔️ Easily assign an identity to your application from a name that you've already reserved in Partner Center.

Third-party installer

Several popular third-party products and installers now support the ability to package a desktop application. You can use them to generate MSI installers or app packages with only a few clicks. While we don't produce documentation on how to use these tools, visit their websites to learn more.

Advanced Installer

Caphyon provides a free, GUI-based, desktop app packaging tool that helps you to generate a Windows app package for your application with only a few clicks. It can use any installer; even ones that run in silent mode, and performs a validation check to determine whether the application is suitable for packaging. The Desktop App Converter also integrates with Hyper-V and VMware. This means that you can use your own virtual machines, without having to download a matching Docker image that can be over 3GB in size.

You can use Advanced Installer to generate MSI and Windows app packages from existing projects. You can also use Advanced installer to import Windows app packages that you generate by using the Microsoft Desktop App Converter. Once imported, you can maintain them by using visual tools that are specifically designed for UWP apps.

Advanced Installer also provides an extension for Visual Studio 2017 and 2015 that can use to build and debug Desktop Bridge apps.

See this video for a quick overview.


Be sure to checkout the recently released Advanced Installer Express Edition.

Cloudhouse Compatibility Containers

For Enterprise customers who have line of business applications that are incompatible with Windows 10 and 10 S, Cloudhouse’s Compatibility Containers enable Windows XP and 7 apps to run on Windows 10 and then converts them to run on the Universal Windows Platform (UWP) for delivery through Microsoft Store for Business, or Microsoft InTune without changing the source code. Register for a Free Trial.

Cloudhouse provides an Auto Packager for packaging line of business applications into Compatibility Containers on the operating systems that the apps runs on today (For example: Windows XP), and then prepare it for conversion to UWP. The Container is then converted to the new Windows app package format by integrating it with Microsoft’s Desktop App Converter tool.

The Auto Packager uses install / capture and runtime analysis to create a Container for the application which includes the application’s files, registry, runtimes, dependencies, and the compatibility and redirection engine required to enable the application to run on Windows 10. The Container provides isolation for the application and its runtimes, so that that they do not affect or conflict with other applications running on the user’s device.

Find out more about how you can deliver business applications through the Microsoft Store for Business Read in our Release blog.


The FireGiant MSIX extension lets you create Windows app packages and MSI packages simultaneously from the same WiX source code. Every time you build, you can target Windows 10 with a Windows app package and earlier versions of Windows with MSI.

The FireGiant MSIX extension uses static analysis and intelligent emulation of your WiX projects to create Windows app packages without the disk space and runtime overhead of containers or virtual machines.

Because the FireGiant MSIX extension doesn't convert your installer by running it, you can maintain your WiX installer without having to repeatedly convert it to Windows app packages. All your users on different versions of Windows get your latest improvements and you don't have to worry about MSI and Windows app packages getting out of sync.

Check out this video and see how in a couple lines of code FireGiant CEO Rob Mensching creates an Appx (Windows app package) version of the popular open-source 7-Zip compression tool and then how he improves both Windows application and MSI packages with changes in the same WiX source code.

RayPack Studio

Raynet's packaging solution, RayPack Studio, supports the creation of packages for desktop applications as one of several possible outcomes of efficient and easy-to-configure conversion and repackaging framework.

Existing virtual environments (VMware Workstation, Hyper-V) can be used to perform automated/bulk conversion without a lengthy environment setup. A component of the studio (RayQC Advanced) is able to make pre-conversion screening and compatibility tests to verify software that is eligible for conversion. Additionally, users can now perform comprehensive collision and compatibility checks with various Windows 10 editions including Anniversary and Creators updates.

Next to the creation of software packages for Windows 10 APPX/UWP format, RayPack Studio can also be used to create classic Windows Installer packages (MSI), patches (MSP), transforms (MST), and App-V packages. Furthermore, this solution comes with a set of software products and components for professional enterprise software packaging. In addition to software packaging and virtualization, RayPack Studio considers all packaging-related tasks: conflict and compatibility checks of software applications and packages (RayQC Advanced), software evaluation (RayEval), and quality assurance (RayQC).

Combined with RayFlow, Raynet´s Enterprise Workflow System, users can efficiently work on the software through the whole enterprise application lifecycle, from package ordering, through evaluation, analysis, packaging, quality assurance, user acceptance tests and deployment. All packages and formats can be stored and deployed directly into SCCM or other solutions. The entire application lifecycle process is tracked and managed by RayFlow. In addition, any order systems such as ServiceNow can be integrated. Raynet builds software packaging factories worldwide with its tools for service providers.

Manual packaging

As a final option, you can convert your application without using any of these tools. If you want that granular control over your conversion, you can create a manifest file, and then run the MakeAppx.exe tool to create your Windows app package.

See Package a desktop application manually.

Add modern Windows 10 experiences

After you create an MSIX package for your desktop app, you can use UWP APIs, package extensions, and UWP components to light up modern and engaging Windows 10 experiences such as live tiles and notifications.

Enhance with UWP APIs

Once you've packaged your app, you can light it up with features such as live tiles, and push notifications. Some of these capabilities can significantly improve the engagement level of your application and they cost you very little time to add. Some enhancements require a bit more code.

See Use UWP APIs in desktop applications.

Integrate with package extensions

If your application needs to integrate with the system (For example: establish firewall rules), describe those things in the package manifest of your application and the system will do the rest. For most of these tasks, you won't have to write any code at all. With a bit of XML in the manifest, you can do things like start a process when the user logs on, integrate your application into File Explorer, and add your application a list of print targets that appear in other apps.

See Integrate your desktop application with package extensions.

Extend with UWP components

Some Windows 10 experiences (For example: a touch-enabled UI page) must run inside of a modern app container. In general, you should first determine whether you can add your experience by Enhancing your existing desktop application with UWP APIs. If you have to use a UWP component, to achieve the experience, then you can add a UWP project to your solution and use app services to communicate between your desktop application and the UWP component.

See Extend your desktop application with UWP components.


To test your application in a realistic setting as you prepare for distribution, it's best to sign your application and then install it. See Test your app.


If you plan to publish your application to the Microsoft Store, make sure that your application operates correctly on devices that run Windows 10 in S mode. This is a store requirement. See Test your Windows app for Windows 10 in S mode.


To give your application the best chance of being published on the Microsoft Store or becoming Windows Certified, validate and test it locally before you submit it for certification.

If you're using the DAC to package your app, you can use the new -Verify flag to validate your package against the packaged desktop application and Store requirements. See Package an app, sign the app, and prepare it for store submission.

If you're using Visual Studio, you can validate your application from the Create App Packages wizard. See Create an app package upload file.

To run the tool manually, see Windows App Certification Kit.

To review the list of tests that the Windows App Certification uses to validate your app, see Windows Desktop Bridge app tests.


You can distribute your application by publishing it the Microsoft Store or by sideloading it onto other systems.
