Xbox Game Package Manager is a Windows desktop utility that gives Xbox developers a graphical interface for building game packages from loose files and uploading them to Microsoft Partner Center, replacing command-line MakePkg and Package Uploader workflows with guided forms.
Xbox Game Package Manager (XGPM) is an open-source Windows desktop application that wraps the GDK's MakePkg and Package Uploader command-line tools in a single graphical interface. Instead of editing JSON configuration files and memorizing switches, you point the app at the folder holding your MicrosoftGame.config, choose an output directory, and let it analyze your loose game files to build an optimized package. From the same window you select a package, branch, and market group, then upload the build straight to Microsoft Partner Center with browser-based sign-in and live progress indicators. The result is a shorter, more transparent path from a local build folder to a submitted Xbox package.
Because XGPM reads your installed GDK, it stays compatible with the GDK version your project already targets, and it handles console and PC packaging workflows the same way. Teams publishing games-as-a-service titles can create packages locally for testing, then upload final builds without leaving the tool. Multi-tenant support covers co-development arrangements where a single account spans several publishing tenants, and the interface ships localized for English, Japanese, Simplified Chinese, and Korean, with light, dark, and high-contrast themes plus narrator and tab-order support. For studios assembling a wider toolkit of documentation-adjacent utilities, something like Microsoft Office 2010 Filter Packs shows how niche installers can still be catalogued and distributed alongside core tooling.
Xbox Game Package Manager removes the friction that made Xbox packaging feel like a scripting exercise. Smart packaging inspects your MicrosoftGame.config and loose files, decides how to split content into chunks, and still gives you manual overrides when a title needs a specific layout, so you no longer hand-write JSON to describe a build. Because packaging and uploading share one window in Xbox Game Package Manager, the branch, market group, and tenant you selected stay visible while progress bars report each stage, meaning a failed upload tells you what went wrong instead of leaving you to parse console output. Browser-based authentication removes the need to generate certificates or store client secrets on a build machine, which simplifies onboarding and reduces the number of credentials floating around a studio. MSIXVC2 support in recent GDK releases keeps the tool aligned with modern package formats, and clear in-app error messages with troubleshooting guidance shorten the debug loop when a submission is rejected.
Key capabilities and highlights.
Point Xbox Game Package Manager at the folder containing your MicrosoftGame.config and it uses your installed GDK to assemble a game package from loose build output. You choose the output directory, so packaged results land wherever your pipeline expects them instead of in a fixed default location.
When a title needs a nonstandard chunk structure, you can supply a custom layout XML file and let the tool drive MakePkg with it. This keeps advanced packaging scenarios, such as separating streaming content from core assets, available through the same interface used for routine builds.
Choose your package, branch, and market group from dropdowns and start the upload without leaving Xbox Game Package Manager. Because the interface already knows which build you selected, there is no path to mistype and no separate command invocation to recall during a busy submission window.
Sign-in happens through your default browser, so the tool never requires a client secret or certificate stored on the machine. Fewer standing credentials on a build box reduces onboarding friction for new team members and limits what has to be rotated when someone leaves a project.
If your account has access to more than one publishing tenant, an advanced option lets you specify the tenant ID for an upload. That matters for co-development and outsourcing arrangements where a single studio account legitimately spans several Partner Center organizations.
Visual indicators track packaging and upload progress stage by stage, so long operations no longer look like a frozen terminal window. When something fails, the interface surfaces a clear message with troubleshooting guidance rather than raw command output, shortening the time spent diagnosing a rejected build.
Packaging and uploading both work in Xbox Game Package Manager without hand-written JSON configuration. Smart packaging analyzes your .config and loose files to work out sensible defaults, while manual override options remain available for teams that need precise control over how content is grouped.
With a current Game Development Kit installed, the tool can create MSIXVC2 packages from loose files and upload them to Partner Center. Studios adopting the newer packaging format can keep using one interface instead of maintaining parallel scripts for each format.

Common questions about Xbox Game Package Manager.
It is a Windows desktop tool for Xbox game developers that handles two jobs in one place: building a game package from loose build files and uploading that package to Microsoft Partner Center. It replaces separate MakePkg and Package Uploader command-line steps with guided forms, progress indicators, and in-app error messages.
No. Xbox Game Package Manager is a graphical front end for the same packaging and upload operations those tools perform, and it relies on your installed Microsoft Game Development Kit to do the work. You still need a GDK installation present, because the app calls into it rather than shipping its own packaging engine.
No. Both workflows are driven through the interface, with no hand-written JSON configuration required. Smart packaging inspects your MicrosoftGame.config and loose files to determine a sensible layout, and manual override options remain available when a title needs a particular chunk structure or a custom layout XML file.
Authentication is browser-based, so the tool opens your default browser to sign you in. That approach removes the need for client secrets or certificates on the build machine. An advanced option also lets you specify a tenant ID when your account has access to more than one publishing organization.
Yes. Packaging and uploading are independent steps, so you can generate a package for local testing or internal QA without touching Partner Center at all. When the final build is ready, you select it along with the target branch and market group and start the upload from the same interface.
The tool integrates with your installed Game Development Kit and is designed to remain backwards compatible with existing GDK versions, so a project does not have to move to a different GDK before the tool can be adopted. Current GDK releases also enable MSIXVC2 package creation and upload through the same interface.
Yes. The interface is localized for English, Japanese, Simplified Chinese, and Korean, and it includes light and dark themes, a high-contrast mode, narrator support, and keyboard tab-order handling. That helps studios with international teams and developers who rely on assistive technology.
