Understanding the 0x80073cf9 Error
When you attempt to install or update an application from the Microsoft Store on Windows 10 or Windows 11, you may encounter an error code 0x80073cf9. This error indicates a deployment failure that prevents the Store from completing the installation or update process. Users often see this error when trying to download games like those from the Xbox app, or when updating system apps such as Microsoft Teams or Paint. The error is frustrating because it can block essential software updates and new installations entirely.
The error 0x80073cf9 is not a sign of hardware failure. Instead, it stems from software conflicts or corrupted system components that interfere with the Microsoft Store’s ability to handle app packages. Understanding the root causes can help you apply the correct fix quickly and avoid unnecessary troubleshooting steps.
Primary Causes of Error 0x80073cf9
Several factors can trigger this error. The most common include a corrupted Microsoft Store cache, disabled Windows Update services, missing or broken "Gaming Services" packages, and interference from third-party applications such as VPNs or antivirus software. Below is a list of the primary causes you should investigate:
- Corrupted Store cache: The Microsoft Store uses a cache to speed up loading, but if this cache becomes damaged, it can prevent installations.
- Disabled Windows Update services: The Store relies on the Windows Update service to download and install packages. If this service is stopped or disabled, deployments fail.
- Missing Gaming Services package: For games and Xbox-related apps, the Gaming Services package is essential. If it is missing or corrupt, you will see error 0x80073cf9.
- Third-party software interference: VPNs, firewalls, or antivirus programs can block the Store’s connection to Microsoft servers or interfere with package verification.
- Outdated Windows version: Older builds may lack necessary components or security updates required by newer Store apps.
Identifying which cause applies to your situation can save time. In most cases, starting with the simplest fix—clearing the cache—resolves the issue. If not, proceed with the other methods detailed below.
Method 1: Clear the Microsoft Store Cache
The quickest and most effective fix for error 0x80073cf9 is to clear the Store’s cache using the built-in wsreset.exe tool. This process removes temporary files that may have become corrupted without affecting your installed apps or settings.
To run wsreset.exe, press the Windows key + R to open the Run dialog box. Type wsreset.exe and press Enter. A blank command prompt window will appear, and after a few seconds, it will close automatically. The Microsoft Store will then open. Try installing or updating the app that previously failed. This method works for a majority of users because cache corruption is the most frequent trigger of error 0x80073cf9.
If the error persists after clearing the cache, move on to the next method.
Method 2: Repair or Reset the Microsoft Store App
Windows provides a built-in repair tool for Store apps. This can fix deeper corruption within the Microsoft Store itself without requiring reinstallation. Follow these steps:
Open Settings by pressing Windows + I. Navigate to Apps > Installed apps (or Apps & features in older versions). Scroll down to Microsoft Store and click the three-dot menu on the right. Select Advanced options. In the new window, you will see a Repair button. Click it first. The system will attempt to fix any issues without losing your data.
If Repair does not resolve the error, use the Reset button below it. Resetting will delete the Store’s local data, including your preferences and login information, but it will not remove your installed apps. After resetting, you will need to sign in again. Many users report success after resetting the Store when simple cache clearing fails.
This method is especially useful when the Store itself becomes unresponsive or shows other errors besides 0x80073cf9.
Method 3: Reinstall Gaming Services via PowerShell
If the error occurs specifically when installing or updating games from the Xbox app or Microsoft Store, the Gaming Services package is likely the culprit. This package manages game installations and can become corrupted or missing. Reinstalling it through PowerShell is a reliable fix.
Before proceeding, ensure you have admin rights. Right-click the Start button and select Windows Terminal (Admin) or PowerShell (Admin). First, check which Gaming Services package is installed by running this command:
get-appxpackage *gamingservices*
Note the full PackageFullName from the output, for example: Microsoft.GamingServices_19.92.28001.0_x64__8wekyb3d8bbwe. Then remove it with:
remove-appxpackage
Replace
This method is highly effective for gaming-related 0x80073cf9 errors. If the automatic reinstall does not trigger, you can also search for Gaming Services in the Microsoft Store and install it manually.
Additional Fix: Update Windows and Check Services
An outdated Windows version can cause compatibility issues with the Store. Ensure your system is fully updated by going to Settings > Windows Update > Check for updates. Install any pending updates, especially cumulative updates and .NET Framework updates. Restart your PC after updating and test the Store again.
Also verify that Windows Update services are running. Press Windows + R, type services.msc, and press Enter. Find Windows Update in the list. Its status should be Running. If not, right-click it and select Start. Set its startup type to Automatic if it is not already. Also check Background Intelligent Transfer Service (BITS) and Cryptographic Services. All three should be running. If they are disabled, the Store cannot download or verify app packages.
| Service Name | Required Status | Startup Type |
|---|---|---|
| Windows Update | Running | Automatic |
| Background Intelligent Transfer Service (BITS) | Running | Automatic (Delayed Start) |
| Cryptographic Services | Running | Automatic |
If any service is stopped, start it manually. After enabling services, restart your PC and retry the Store operation.
Additional Tips and Precautions
If none of the above methods resolve error 0x80073cf9, consider temporarily disabling third-party antivirus software or VPNs. Sometimes security software blocks the Microsoft Store from writing to protected system folders. Disable any such software, attempt the installation, and then re-enable it afterward. You can also try running the Windows Store Apps Troubleshooter built into Windows 10 and 11. Go to Settings > System > Troubleshoot > Other troubleshooters, find Windows Store Apps, and run it.
Another less common fix involves creating a new user account. A corrupted user profile can prevent Store apps from deploying. Create a temporary local administrator account, sign in, and try the installation. If it works, migrate your data to the new account or repair the original profile.
For persistent cases, a system restore to a point before the error occurred may help, but this should be a last resort as it can revert other system changes.
