Purchasing or updating apps in the Microsoft Store on Windows 11 may sometimes fail with error code 0x80070422, often accompanied by messages like “Purchase couldn’t be completed” or “Microsoft Store needs to be updated.” This error is directly linked to disabled or misconfigured system services that the Store depends on, especially the Windows Update service. When these services are not running, transactions and updates in the Store are blocked, affecting your ability to install or buy apps.

Check and Start Required Windows Services

Open the Windows Services Manager by pressing Win + R, typing services.msc, and pressing Enter. This tool lets you manage all background services running on your system.

In the Services window, locate these key services one by one:

Windows Update
Microsoft Store Install Service
Background Intelligent Transfer Service
Cryptographic Services
Windows Installer

For each service, double-click to open its properties. Set the “Startup type” to Automatic (or Manual for Windows Installer). If the service isn’t running, click Start. Click OK to apply changes.

After configuring the services, restart your computer to ensure all changes take effect and services initialize properly.

Reset the Microsoft Store Cache

Corrupted cache files can prevent the Store from processing purchases and updates. Clearing the cache often resolves persistent Store issues.

Press Win + R to open the Run dialog, type wsreset.exe, and press Enter. A blank Command Prompt window will appear for a few seconds, then the Store will reopen automatically. This process clears temporary files used by the Store.

Try your purchase or update again after the reset.

Run Windows Store Apps Troubleshooter

Windows 11 includes a built-in troubleshooter that can automatically detect and fix many common problems affecting the Microsoft Store and related apps.

Go to Settings > System > Troubleshoot > Other troubleshooters.

Scroll to find Windows Store Apps and click Run.

Follow the on-screen prompts. The troubleshooter will scan for issues and attempt repairs. If it finds and fixes a problem, test the Store again.

Repair or Reset Microsoft Store and Gaming Services

Corrupted app data or services can block purchases. Repairing or resetting the Microsoft Store and related services like Gaming Services can restore normal functionality.

Open Settings > Apps > Installed apps.

Find Microsoft Store and click the three-dot menu, then select Advanced options.

Click Repair. If the problem persists, click Reset. Repeat these steps for Gaming Services if you use Xbox or game-related features.

Try your Microsoft Store purchase or update again.

Update Windows 11

Outdated system files or missing updates can disrupt the Store’s ability to process purchases and updates.

Open Settings > Windows Update and click Check for updates. Download and install all available updates.

After updates are installed, restart your computer. This ensures new system files are loaded and any pending changes are applied.

Run System File Checker and Repair Tools

Corrupted or missing system files can prevent required services from starting, causing persistent Store errors.

Open the Start menu, type cmd, right-click Command Prompt, and select Run as administrator.

Enter the following command to scan and repair system files:

sfc /scannow

This process may take several minutes. Wait for it to finish and follow any repair instructions shown.

For deeper repairs, run the following commands one by one, pressing Enter after each:

DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

These commands use Windows’ Deployment Image Servicing and Management tool to check and restore system integrity.

Check for Problematic Files in the System Root

Unexpected files in the root directory of your system drive (usually C:\) can interfere with Store and Gaming Services. For example, a file named Program with no extension can block essential services from starting.

Open File Explorer and navigate to C:\.

Look for files named Program or Program1 without extensions. If found, right-click and select Delete.

Restart your computer and test the Microsoft Store.

Additional Steps and Tips

Temporarily disable firewall or antivirus software to see if they are blocking Store connections. Re-enable them after testing.
Sign out and back into your Microsoft account in the Store app to refresh authentication tokens.
If the error persists on the Xbox app or other Store apps, consider using the official Gaming Services Repair Tool to fix gaming-related Store issues.
If you use IPv6 and experience persistent errors, try disabling IPv6 in your network adapter settings as a troubleshooting step.

By systematically checking services, clearing cache, updating Windows, and repairing Store components, you can restore full purchasing and updating functionality to the Microsoft Store in Windows 11. If issues continue, Microsoft’s official support channels and repair tools can provide further assistance.
