How to Fix Error Code: 0x80073CFB from Microsoft Store?

The installation or update process in Microsoft Store or Xbox App may suddenly stop at 100% with error code 0x80073CFB on the screen. This code means the app deployment has failed, typically due to internal conflicts or corrupted app packages.

The most confirmed cause is a leftover or active Xbox Companion App, which breaks dependencies needed by newer versions of Xbox or Store apps. Other known triggers include corrupted cache, registry inconsistencies, or problems during a recent Windows update.

1. Clear Microsoft Store Cache Files

Cache files are temporary files stored by Windows. Sometimes, the Microsoft Store cache can become corrupted due to reasons like power failures or sudden shutdowns. There is a strong possibility you are seeing the 0x80073CFB error because of corrupted Microsoft Store cache files.

1. Press the Windows key and type Command Prompt in the search box.
2. Open Command Prompt as an administrator by pressing Ctrl + Shift + Enter.
3. Enter the following command to clear the Microsoft Store cache:

   wsreset

   

4. Close the Command Prompt and then check if the error persists.

2. Reset or Repair Microsoft Store

You can also use the Reset and Repair options available for Microsoft Store. We recommend trying the repair option first. If that doesn’t solve the error, use the reset option.

1. Open Settings by pressing Windows + I.
2. Click on Apps > Apps & Features.
3. Find Microsoft Store in the list of installed apps.
4. Click on Microsoft Store, then select Advanced options to view more settings.

   

5. At the bottom of the screen, you will see Reset and Repair buttons.

   

6. Click on Repair first. If the error persists, then click on the Reset button.

3. Run Windows Apps Troubleshooter

The Windows Apps Troubleshooter is a tool that helps identify and fix problems with Microsoft Store apps.

1. Open Settings by pressing Windows + I.
2. Click on Update & Security.
3. Click on Troubleshoot from the left panel.
4. Select Additional troubleshooters to see more options.

   

5. Find the Windows Store Apps option under Find and fix other problems, and click on it.
6. Click Run the troubleshooter.

   

7. The troubleshooting process will start. Once it’s done, check if the error is resolved.

4. Disable Proxy Server

A proxy server acts as an intermediary between your computer and the internet, and if enabled, it can sometimes prevent downloads or access to websites.

1. Open Settings by pressing Windows + I.
2. Click on Network & Internet.
3. Click on Proxy from the left panel.
4. In the center of the screen, locate the Use a proxy server option.

   

5. If the Use a proxy server switch is On, turn it Off.

5. Run System File Checker

System File Checker is a tool developed by Microsoft for Windows. It scans all system files and replaces corrupted files with a cached copy.

1. Press the Windows key and type Command Prompt in the search box.
2. Open Command Prompt as an administrator by pressing Ctrl + Shift + Enter.
3. Type the following command to begin the scan:

   sfc /scannow

   

4. Wait for the process to complete, then check if the error is fixed.

6. Clear Software Distribution Folder

The Software Distribution folder is found in the Windows directory and stores files needed for Windows Updates. Clearing this folder can sometimes resolve the 0x80073CFB error.

1. First, you need to stop the Windows Update service. If you don’t, you may interrupt the installation of Windows updates.
2. Press the Windows key and type Windows PowerShell in the search box.

4. Type the following command to stop the Windows Update service:

5. Type the following command to rename the Software Distribution folder:

   ren c:\windows\SoftwareDistribution softwaredistribution.old

   

6. Now restart the Windows Update service by typing:

   net start wuauserv

7. Reinstall Microsoft Store

Reinstalling the Microsoft Store can also fix the 0x80073CFB error. This requires using PowerShell, as the Microsoft Store can’t be reinstalled from the Control Panel or Settings.

1. Press the Windows key and type Windows PowerShell in the search box.
2. Open Windows PowerShell as administrator by pressing Ctrl + Shift + Enter.
3. To uninstall Microsoft Store, type and execute this command:

   Get-AppxPackage -allusers *WindowsStore* | Remove-AppxPackage

   

4. Restart your computer.
