How to Fix No Such Interface Supported File Explorer Error in Windows 11

File Explorer in Windows 11 may display the “No Such Interface Supported” error when system files, user profiles, or application components become corrupted or misconfigured. This issue can prevent you from opening files, launching certain apps, or even accessing basic system functions. The error often appears after system updates, registry modifications, or when DLL files required by File Explorer or other programs fail to load correctly. Addressing this problem involves targeted repair steps that restore normal system operation and prevent potential data loss.

Repair or Reset the Affected Application

Problems with specific applications, such as Microsoft Photos, Media Player, or third-party viewers, can trigger the “No Such Interface Supported” error when opening files directly from File Explorer. Repairing or resetting the problematic app often restores its normal operation and resolves the error.

Open the Windows Settings app by pressing Windows + I on your keyboard.

Click Apps in the left sidebar, then select Installed apps or Apps & features depending on your Windows version.

Find the affected app in the list. Click the three-dot menu or select the app, then choose Advanced options.

Scroll down to the Reset section. Click Repair to attempt a non-destructive fix that keeps your app data. If the issue persists, use Reset to restore the app to its default state.

Restart your computer and test the app again. If the error remains, proceed to reinstall the application. Uninstall it via appwiz.cpl in the Run dialog, restart your PC, and download the latest version from the official source.

Run System File Checker (SFC) to Repair Corrupted System Files

Corrupted or missing system files can disrupt Windows interfaces and cause File Explorer errors. The System File Checker tool scans for and repairs these files, restoring expected behavior.

Type cmd in the Windows search bar, then right-click and select Run as administrator.

At the command prompt, enter the following command and press Enter:

sfc /scannow

This command scans protected system files and automatically repairs any detected corruption. Wait for the process to complete, then restart your computer. Check if File Explorer and affected applications now function correctly.

Re-Register DLL Files Required by File Explorer

File Explorer and many Windows apps rely on specific DLL (Dynamic Link Library) files. If these files are unregistered or damaged, the system may throw interface errors. Re-registering DLLs can restore required functionality.

Open Command Prompt as an administrator, as described in the previous section.

regsvr32 c:\windows\system32\actxprxy.dll

If the error persists, you can re-register all DLL files within the system directory by running:

FOR /R C:\ %G IN (*.dll) DO "%systemroot%\system32\regsvr32.exe" /s "%G"

This process may take several minutes and will not display output for each file. Once complete, restart your computer and test File Explorer and related apps.

Caution: Before running bulk DLL registration commands, create a system restore point and back up important data. Incorrect DLL registrations can cause further issues if system files are already unstable.

Try Opening Files from the Desktop or Directly Within Applications

Sometimes, the error only appears when attempting to open files from certain locations in File Explorer. Moving files to the desktop or opening them directly from within the target application can serve as a temporary workaround.

Move the problematic file from its current folder to your desktop.

Double-click the file on the desktop or use the application’s Open menu to browse and select the file.

This approach helps determine if the issue is tied to folder permissions or File Explorer itself. If the file opens from the desktop or through the app, the problem may be isolated to File Explorer or the original folder’s settings.

Note: Avoid storing important files permanently on the desktop to minimize clutter and reduce the risk of accidental deletion.

Check and Repair Disk Errors Using CHKDSK

Disk errors can interfere with file access and system operations, resulting in interface errors. Running the Check Disk utility identifies and repairs these issues to restore normal file handling.

Open Command Prompt as an administrator.

Enter the following command, replacing C: with your system drive letter if different:

chkdsk C: /r /v

If prompted to schedule the scan at the next restart, type Y and press Enter. Restart your computer to allow CHKDSK to scan and repair the drive. After the process completes, check if the error has been resolved.

Create a New User Profile to Rule Out Account Corruption

User profile corruption can prevent File Explorer and apps from accessing necessary interfaces. Creating a new user account helps determine if the problem is tied to your current profile.

Open Settings and go to Accounts > Other users.

Click Add account and follow the prompts to create a new local or Microsoft account.

Sign in with the new account and attempt to open files or launch apps that previously triggered the error. If everything works as expected, your original user profile may be corrupted. You can migrate your files to the new account or attempt to repair the old one using system restore or profile repair tools.

Additional Tips and Maintenance

Always keep Windows and all applications updated to the latest versions to avoid known bugs.
Run regular malware scans, as malicious software can corrupt system files and interfaces.
Back up important data before making major changes or running system repair commands.
If none of these steps resolve the issue, consider restoring your system to a previous restore point or performing a repair install of Windows 11.

Addressing the “No Such Interface Supported” error in Windows 11 restores access to File Explorer and affected apps, making file management and daily tasks reliable again. If the problem returns, reviewing recent system changes or consulting Microsoft support may help you identify lingering issues.
