Fix Microsoft Store Error 0x80073D02 on Windows 11 (2025 Guide)

Are you seeing the error code 0x80073D02 when trying to update or install apps from the Microsoft Store?
You’re not alone. This common issue affects many Windows 10 and 11 users, especially after major updates. In this guide, we’ll walk you through step-by-step solutions that are safe, effective, and easy for beginners to follow—even if you’re not tech-savvy.

What Causes Error 0x80073D02?

This error typically occurs due to one of the following reasons:

• The app you’re trying to update is still running in the background
• Temporary glitch in the Windows system or Store cache
• Corrupted Microsoft Store cache or configuration
• Recent Windows Update has disrupted Store functions

Solution 1: Close the App Completely

The most common cause is that the app is still running while you’re trying to update it. Here’s how to fully close it:

1. Manually close the app

If the app is open, close it normally from the window. Try the update again.

2. Force close from Task Manager

Press Ctrl + Shift + Esc to open Task Manager → Go to “Processes” → Right-click the app → Select “End task”.

3. Restart your PC

Restarting your system helps reset background processes that may interfere with the Store.

Solution 2: Clear Microsoft Store Cache

To refresh the Store cache:

• Press Windows + R to open the Run dialog
• Type wsreset and press Enter
• A command window will appear briefly and then the Store will reopen automatically

If this solves the problem, the cache was likely corrupted.

Solution 3: Check Windows Update

Make sure your Windows system is up-to-date:

• Press Windows + I → Go to Windows Update
• Click Check for updates
• Install any available updates, then restart your PC

Sometimes, outdated system files can prevent the Microsoft Store from working correctly. Keeping your Windows OS fully updated ensures compatibility with Store apps and resolves many hidden background issues.

Solution 4: Reset the Microsoft Store App

If the Store settings are corrupted, try resetting the app:

• Open Settings → Apps → Installed apps
• Find Microsoft Store → Click Advanced options
• Click the Reset button
• Restart your PC and try again

Resetting the Microsoft Store clears all stored settings and cache, essentially giving you a fresh start. It won’t delete your installed apps, but it can fix hidden corruption or misconfigurations causing the error.

Solution 5: Run the Troubleshooter

Windows has a built-in tool for detecting and fixing Microsoft Store problems:

• Go to Settings → System → Troubleshoot → Other troubleshooters
• Find Windows Store Apps and click Run

This is often the easiest fix for many users.

Solution 6: Uninstall and Reinstall the App

If only one app is causing the issue, uninstall and reinstall it:

• Open Settings → Apps
• Select the app → Click Uninstall
• Restart your PC and reinstall the app from the Store

This method works best when only a single app is affected. Reinstalling removes corrupted data and ensures you’re using the latest version, which often resolves persistent update issues.

Advanced Fixes

▶ Clear Your DNS Cache

Sometimes, your computer may store old or incorrect network information that causes app download problems. Clearing your DNS cache helps your PC reconnect properly to Microsoft’s servers.

Don’t worry—this is safe and won’t delete any personal files. Just follow these steps:

• Press Windows + S and type cmd
• Right-click Command Prompt and select Run as administrator
• In the black window, type the following command and press Enter:

You should see a message like “Successfully flushed the DNS Resolver Cache.” This means your network cache is cleared and may help resolve download issues from the Microsoft Store.

▶ Re-register the Microsoft Store App (Advanced)

If none of the previous solutions worked, you can try re-registering the Microsoft Store. This means telling Windows to repair or refresh the Store app’s internal files—without deleting any of your installed apps or data.

Use this method only if you’re comfortable running a command in PowerShell.

Steps:

• Right-click the Start button and select Windows PowerShell (Admin) or Terminal (Admin)
• Copy and paste the following command, then press Enter:

This command tells Windows to re-register the Microsoft Store and fix any broken settings or registration issues. If successful, it can restore full functionality to the Store app.

Note: You won’t lose any apps, and this won’t affect your personal data. However, be sure to copy the command exactly as shown.

Summary

Error 0x80073D02 can usually be fixed by closing the app, clearing cache, updating Windows, or resetting the Store. If basic steps don’t help, try the advanced methods or contact Microsoft support.
