Error code 0x80004002 means Windows has encountered a 'No Such Interface Supported' failure, most commonly triggered when the Windows Update COM (Component Object Model) interface is missing, corrupted, or blocked. This typically prevents Windows Update from running correctly and can also affect other system components that rely on COM communication. The good news is that this error is almost always fixable through built-in Windows tools, registry repairs, or system file restoration without needing professional help.

Tools You'll Need

How to Fix Error Code 0x80004002

  1. Run the Windows Update Troubleshooter

    Save all open work before restarting your PC at the end of this step.

  2. Restart the Windows Update Services

  3. Clear the Windows Update Cache

    Do not delete the SoftwareDistribution folder itself — only the contents of the Download subfolder.

  4. Run System File Checker (SFC)

    Do not close the Command Prompt window while the scan is running. Interrupting it can cause additional system issues.

  5. Run the DISM Tool to Repair Windows Image

    Ensure you have a stable internet connection before running the RestoreHealth command. A dropped connection mid-repair can cause incomplete repairs.

  6. Re-register Windows Update DLL Files

  7. Check for Conflicting Third-Party Software

    Only disable your antivirus temporarily and in a trusted network environment. Re-enable it as soon as testing is complete.

  8. Reset Windows Update Components Using a Script

    Only download the reset script from the official Microsoft Support website (support.microsoft.com). Do not use third-party versions of this script.

  9. Perform a Windows Repair Upgrade (In-Place Upgrade)

    Back up all important files to an external drive or cloud storage before starting an in-place upgrade, even though it is designed to preserve your data.

When to Call a Professional

Contact Microsoft Support or a professional PC technician if: (1) The in-place repair upgrade fails or causes additional errors, (2) DISM reports it cannot repair the Windows image even with an internet connection, (3) The error occurs alongside Blue Screen of Death (BSOD) crashes or hardware failure symptoms, (4) You are managing a business or enterprise environment where group policy, domain settings, or WSUS configurations may be causing the issue — an IT administrator should handle those cases. You can reach Microsoft Support at support.microsoft.com.

Frequently Asked Questions

What does Windows error code 0x80004002 mean?
Error 0x80004002 means 'No Such Interface Supported' in Windows. It occurs when a program or Windows itself tries to use a COM (Component Object Model) interface that is missing, corrupted, or not registered on your system. It most commonly appears during Windows Update but can also show up with other applications.
Will error 0x80004002 go away on its own?
No, error 0x80004002 will not resolve itself. It indicates a structural problem with system files or COM registrations that requires active troubleshooting steps such as running SFC, DISM, or re-registering DLL files to fix.
Can antivirus software cause Windows error 0x80004002?
Yes. Some aggressive antivirus or security programs block COM interface communications, which can trigger error 0x80004002. Try temporarily disabling your third-party antivirus and running Windows Update to test if it is the cause. If updates succeed without the antivirus, adjust its settings to whitelist Windows Update processes.
Is it safe to re-register DLL files to fix 0x80004002?
Yes, re-registering the specific Windows Update DLL files listed in the fix steps is safe and is a method recommended by Microsoft. You are simply re-registering existing system files, not installing or modifying them. Make sure you run Command Prompt as Administrator and use only the exact DLL names listed.
Will a Windows in-place repair upgrade delete my files?
No. A Windows in-place repair upgrade (also called a repair install) is specifically designed to reinstall Windows system files while keeping all of your personal files, installed applications, and settings intact. However, it is always best practice to back up your important data before performing any system repair as a precaution.
