• Click on “System”.
• Scroll down and click on “Troubleshoot”.
• Select “Other troubleshooters”.

The “wsreset.exe” command resets the Windows Store without changing account settings or deleting installed apps. It’s a safe and effective way to resolve many Store-related issues.

Solution 3. Update or Reinstall .NET Framework

The .NET Framework is crucial for many Windows applications. Ensuring it’s up-to-date or reinstalling it can often resolve the 0x80040155 error:

Advanced Methods to Resolve the 0x80040155 “Interface Not Registered” Error

If the beginner-friendly methods didn’t resolve the issue, try these more advanced techniques. These methods require a bit more technical knowledge, so proceed with caution.

Adv. Solution 5. Re-register Windows Store

Re-registering the Windows Store can fix issues with corrupted files or settings. Here’s how to do it:

• Right-click the “Start” button and select “Windows PowerShell (Admin)”.

• Copy and paste the following command:
  Get-AppxPackage -allusers Microsoft.WindowsStore | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
• Press ‘Enter’ and wait for the process to complete.

• Restart your computer.

The command re-registers the Windows Store for all system users, potentially resolving any registration issues causing the 0x80040155 error.

Adv. Solution 6. Run System File Checker (SFC) and DISM

Use these built-in Windows tools to repair corrupted system files:

• Open “Command Prompt” as administrator.

• Run the SFC scan: sfc /scannow

• Wait for the process to complete. It might take several minutes.
• If issues persist, run the following DISM commands:
  DISM /Online /Cleanup-Image /CheckHealth
  DISM /Online /Cleanup-Image /ScanHealth
  DISM /Online /Cleanup-Image /RestoreHealth

• Restart your computer after the process is complete.

The “System File Checker” (SFC) scans for and repairs corrupted system files. If SFC doesn’t resolve the issue, the “Deployment Image Servicing and Management” (DISM) tool can repair the Windows image itself.

Adv. Solution 7. Modify Your PC’s Registry

Caution: Modifying the registry can be risky. Always back up your registry before making changes. Here’s how to do it:

• Press ‘Windows + R’, type “regedit”, and press ‘Enter’.

• Close “Registry Editor” and restart your computer.

The registry modification can resolve issues related to DCOM settings, which might be causing the 0x80040155 error.

Adv. Solution 8. Perform a Clean Boot

A clean boot starts Windows with minimal drivers and startup programs. Such a procedure can help identify if a third-party application is causing the 0x80040155 error:

• Press ‘Windows + R’, type “msconfig”, and press ‘Enter’.

• Go to the “Services” tab.
