Method 2: Check and Restart Windows Defender Firewall Service

Since Error 0x80073D0A directly relates to Windows Defender Firewall, ensuring this service is running is crucial.

Step 1: Press Win + R, then type services.msc and press Enter to open the Services window.

Step 2: Scroll down to find Windows Defender Firewall. Right-click the service and select Properties.

Step 3: In the properties window, set the Startup type to Automatic. If the service status shows as Stopped, click the Start button.

Step 4: Confirm your changes by clicking Apply followed by OK. Restart your computer and try installing or updating apps again.

Method 3: Reset Microsoft Store Cache

Corrupted cache files often cause issues with app installations and updates. Clearing the cache can resolve these problems.

Step 1: Press Win + R, type wsreset.exe, and hit Enter. A command prompt window will briefly appear, and the Microsoft Store will open automatically afterward.

Step 2: Once the Microsoft Store opens, try installing or updating the problematic app again to see if the issue is resolved.

Re-registering Microsoft Store apps can fix deeper issues related to app installation and updates.

Step 1: Right-click the Start button and select Windows Terminal (Admin) or Windows PowerShell (Admin).

Step 2: Enter the following command and press Enter:


Get-AppXPackage -allusers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Wait until the process completes, then restart your computer and attempt app installation again.

Method 5: Temporarily Disable or Uninstall Third-Party Firewall or Antivirus Software

Third-party security software, such as Norton or Kaspersky, can sometimes interfere with Microsoft Store operations.

Step 1: Temporarily disable your third-party antivirus or firewall software. This process varies depending on your software; typically, you can right-click the software's icon in the system tray and select an option to disable protection temporarily.

Step 2: After disabling the software, restart your computer and attempt to install or update apps from the Microsoft Store. If the issue resolves, consider adding Microsoft Store to the software's exception or exclusion list to prevent future conflicts.

Method 6: Perform System File Checker (SFC) and DISM Scans

Corrupted system files can also trigger Microsoft Store errors. Running SFC and DISM scans can repair these files.

Step 1: Open Command Prompt as an administrator. Type the following command and press Enter:


sfc /scannow

Allow the scan to complete. If issues are found, the tool will attempt automatic repairs.

Step 2: Next, run the DISM tool by entering the following command:


DISM /Online /Cleanup-Image /RestoreHealth

Wait for the process to finish, then restart your PC and check if the Microsoft Store issue is resolved.

Method 7: Create a New User Account

If all else fails, creating a new Windows user account can resolve profile-specific issues affecting Microsoft Store.

Step 1: Open the Settings app and navigate to Accounts > Family & other users. Click Add someone else to this PC. On Windows 11, you will find the option to Add other user on the Accounts page.

Step 2: Follow the prompts to create a new user account. Once created, sign out of your current account and log into the new one. Check if Microsoft Store functions correctly.

With these methods, you should successfully resolve Microsoft Store Error 0x80073D0A. Regularly updating your system and maintaining security services can help prevent similar issues in the future.
