Fix No Such Interface Supported Error in Windows (5 Easy Methods)

If you’ve ever tried opening an app, installing software, or running a command on Windows only to be greeted by the frustrating message “No Such Interface Supported,” you’re not alone. This error is more common than many users realize and can appear on Windows 7, 8, 10, and 11.

The good news? In most cases, it’s fixable without reinstalling Windows.

In this guide, we’ll explain what the “No Such Interface Supported” error means, why it happens, and five proven ways to fix it—step by step.

What Does “No Such Interface Supported” Mean?

The No Such Interface Supported error usually points to a problem with COM (Component Object Model) components in Windows. COM components allow applications and system services to communicate with each other.

When Windows can’t find, register, or access a required interface, it throws this error.

You’ll often see it when:

• Opening apps like File Explorer, Control Panel, or third-party software
• Installing or uninstalling programs
• Running system tools or scripts
• After a Windows update or system crash

Common Causes of the “No Such Interface Supported” Error

Before jumping into fixes, it helps to understand what triggers the issue:

• Corrupted or missing system files
• Improperly registered DLL files
• Broken or outdated device drivers
• Faulty Windows updates
• Corrupted user profile
• Malware or registry damage

Now let’s fix it.

1. Restart Windows Explorer (Quick Fix)

Sometimes the issue is temporary and tied to Windows Explorer.

Steps:

1. Press Ctrl + Shift + Esc to open Task Manager
2. Find Windows Explorer
3. Right-click it and choose Restart

This refreshes the shell interface and can instantly resolve the error—especially if it appears when opening folders or system windows.

2. Re-register DLL Files (Most Effective Fix)

Since this error is COM-related, re-registering DLL files often solves it.

Steps:

1. Press Windows + X
2. Select Command Prompt (Admin) or Windows Terminal (Admin)
3. Run this command:

regsvr32 /i shell32.dll

4. Press Enter and restart your PC

If the error persists, also try:

regsvr32 ole32.dll
regsvr32 actxprxy.dll

These files are essential for Windows interfaces and application communication.

3. Run System File Checker (SFC Scan)

Corrupted system files are a major cause of the No Such Interface Supported error.

Steps:

1. Open Command Prompt (Admin)
2. Run:

codesfc /scannow

3. Wait for the scan to complete
4. Restart your computer

SFC automatically repairs missing or damaged Windows files that may be breaking interfaces.

4. Update or Roll Back Device Drivers

Faulty drivers—especially graphics or chipset drivers—can trigger this error.

To Update Drivers:

1. Press Windows + X
2. Click Device Manager
3. Right-click key drivers (Display adapters, System devices)
4. Choose Update driver

To Roll Back Drivers (after a recent update):

1. Right-click the driver
2. Select Properties
3. Go to the Driver tab
4. Click Roll Back Driver (if available)

This is particularly useful if the error appeared after a Windows update.

5. Create a New User Profile (Last Resort Fix)

Sometimes the issue is tied to a corrupted Windows user profile.

Steps:

1. Open Settings
2. Go to Accounts → Family & other users
3. Click Add someone else to this PC
4. Create a new local or Microsoft account
5. Log into the new account and test

If the error disappears, your old profile is likely corrupted.

Bonus Tip: Scan for Malware

Malware can damage system interfaces and registry entries. Run a full scan using:

• Windows Security
• Or a trusted third-party antivirus

When Should You Reinstall Windows?

A full Windows reinstall should be your last option. Only consider it if:

• All fixes above fail
• The error affects multiple system apps
• Windows becomes unstable overall

In most cases, one of the five solutions above fixes the issue.

Final Thoughts

The No Such Interface Supported error may look serious, but it’s usually caused by corrupted system components or misconfigured files, not hardware failure. With the right steps, you can fix it in minutes and get back to work without stress.

If you’re running a business system or mission-critical software, fixing this early helps avoid downtime and data loss.
