How to Fix WhatsApp Error Code 0x80073cfa on Windows

Step 1: Delete Residual Files and Clean the Registry

One of the main causes of WhatsApp error code 0x80073cfa is residual files from previous installations. These leftover files can create conflicts and prevent WhatsApp from installing or uninstalling.

To remove residual files:

Open File Explorer and go to:
- C:\Users\<Your_Account>\AppData\Local\Packages
- C:\Program Files\WindowsApps (This folder is hidden; you may need admin permissions)
Look for any WhatsApp-related folders (e.g., 5319275A.WhatsAppDesktop), and delete them.

Note: Deleting files from the WindowsApps folder requires taking ownership of the folder. Right-click the folder > Properties > Security tab > Advanced > Change Owner > Delete the folder.

Next, clean the Windows registry:

Press Win + R, type regedit, and press Enter.
Navigate to:
- HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppModel\Repository\Packages
Find any entries related to WhatsApp and delete them.

Warning: Be sure to back up your registry before making any changes. You can do this by selecting File > Export in the Registry Editor.

Step 2: Re-register the Microsoft Store

If WhatsApp fails to install through the Microsoft Store, it might indicate an issue with the Store itself. Re-registering the Microsoft Store can resolve installation problems.

To re-register the Microsoft Store:

Press Win + X and select Windows PowerShell (Admin).
Type the following command and press Enter:powershellCopy codeGet-AppxPackage -allusers Microsoft.WindowsStore | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Restart your computer and try to install WhatsApp again from the Microsoft Store.

Step 3: Perform a Clean Boot

Background processes and third-party software can sometimes interfere with WhatsApp installations or uninstalls. Performing a clean boot allows you to troubleshoot by disabling unnecessary services.

To perform a clean boot:

Press Win + R, type msconfig, and press Enter.
In the System Configuration window, go to the Services tab, check Hide all Microsoft services, and then click Disable all.
Go to the Startup tab, click Open Task Manager, and disable all startup items.
Close Task Manager and click OK in the System Configuration window.
Restart your computer and try installing WhatsApp again.

Step 4: Run System File Checker (sfc/scannow)

The sfc/scannow command is a built-in tool in Windows that checks and repairs corrupted system files. Running this tool can fix issues that prevent WhatsApp from installing or functioning properly.

To run the System File Checker:

Press Win + X and select Command Prompt (Admin) or Windows PowerShell (Admin).
Type the following command and press Enter:shellCopy codesfc /scannow
Wait for the process to complete, then restart your computer.

Step 5: Check for Windows Updates

Outdated system files or missing updates can sometimes cause installation problems. Make sure your system is up to date to avoid compatibility issues with WhatsApp.

To check for Windows updates:

Go to Settings > Update & Security > Windows Update.
Click Check for updates and install any available updates.
Restart your computer and try installing WhatsApp again.

Download the Media Creation Tool and select Create installation media for another PC.
