One of the features of Steam on Windows is that it allows you to add games manually, but it is limited to EXE-based games which are not downloaded from the Microsoft Store. Now that Microsoft Store is one of the major sources for Games, it should make sense to add those games to Steam as well. However, there is no direct support for the games installed from the store.
Add Microsoft Store Game apps to Steam
In this post, I am sharing a trick that allows you to do this. Before we start, make sure you have installed the game on Windows PC – and here I am using Age of Empires as an example. Remember, you will need admin privileges to do this.
Locate the Windows UWP Game
Games and Apps installed from the store are available as a package. We will need first to locate it. The path should like as below:
C:\Users\<USERNAME>\AppData\Local\Packages
You can also type %appdata% in the Run prompt, and then go back one step to find the Local folder, and then enter into Packages.
Now look for the game package. If it’s difficult, but you can search by the name of the game.
For Age of Empires the folder is named as Microsoft.MSDallas_8wexxxxxxx.
Locate App Manifest for the Game
Next, we will access a hidden folder that includes all the games, and apps.
It is usually located at C:\Program Files\WindowsApps OR <DISK>:\WindowsApps.
<Disk> is applicable when you have selected a different drive for apps, and games.
You will need to have admin privileges, and if you are not allowed to access it, you will have to change the ownership of the App folder from Trusted Installer to your account.
Once inside, look for the folder which the same name which we found above. In this case, it will be “Microsoft.MSDallas_8wexxxxxxx.”
Next, locate the AppxManifest.xml file in the folder. Open it with a text editor. I would suggest using Notepad. Do not edit anything there – and save is as a .txt file.
Now, find this tag in the file “<Application Id=”
Copy the application ID which in this case is only App. Note it down on a separate Notepad or remember it.
Now in Notepad follow this template:
shell:AppsFolder\PACKAGE!APPID
For Age of Empires, the package will be ‘Microsoft.MSDallas_1.3.5292.2_x64__8wekyb3d8bbwe’ and the AppID will be ‘App’.
So the string for Age of Empires will become:
shell:AppsFolder\Microsoft.MSDallas_1.3.5292.2_x64__8wekyb3d8bbwe!App
Please check what it is on your computer.
Add to Steam
This is where we will trick Steam. Add any EXE program like Windows Explorer or Chrome to the game library. Once it’s in the list, right-click on that application, and select Properties.
Remove everything from the Start in section, and overwrite with the text we created in the Target section.
In our case, it will be:
shell:AppsFolder\Microsoft.MSDallas_1.3.5292.2_x64__8wekyb3d8bbwe!App
You can also rename the name to the name of the game.
Post this; you will be able to launch Windows Store games from Steam directly. However, you will have to repeat this process for every game.
There are few drawbacks though. You don’t get full Steam features related to Steam here such as VR support. So you will not see any info from Steam like you see for other games which you had downloaded from there – but Steam will still manage to launch the game for you, and in most cases, the in-game overlay will be available.
How do I add Microsoft Store games from Steam to Windows?
To add Microsoft Store games to Steam in Windows 11/10 PC, you need to locate the game first. IN most cases, you can find it in the AppData folder. Then, you need to find the manifest of the game. To access it, you need to have the correct permission. Following that, you must copy the Application ID and edit the manifest file like this: shell:AppsFolder\PACKAGE!APPID. Once done, you need to open Steam on your PC and add the game.
Can Microsoft Store play with Steam?
No, it is not possible as of now. If you have a game on Steam and someone else has it from Microsoft Store, you cannot link them. In other words, it is not possible to get cross-platform support from Steam or Microsoft Store.
