Files in file explorer will not open, nor will the submenu open when right-clicking them (Windows 10)

Troubleshooting File and Context Menu Accessibility Issues in Windows 10

Introduction

Experiencing issues where files within File Explorer no longer open, and right-click context menus do not appear, can significantly disrupt your workflow. Such problems may manifest after system updates, software installations, or other changes, and resolving them promptly is essential for maintaining productivity. In this article, we will explore common causes of these issues and provide detailed troubleshooting steps to restore normal functionality in Windows 10.

Scenario Overview

A typical scenario involves a user discovering that:

• Files cannot be opened by double-clicking or through the search menu.
• Right-clicking files in File Explorer does not open the context menu or submenu.
• Program applications (e.g., Notepad) launch without issues.
• Attempts to fix the problem by restarting Windows Explorer or shutting down the PC temporarily fail.
• A full system restart often resolves the issue, at least temporarily.

This kind of behavior suggests underlying issues that may involve file associations, system processes, or registry inconsistencies.

Potential Causes

Several factors can lead to such anomalies, including:

1. Corrupted File Explorer or Shell Extensions: Faulty or incompatible shell extensions can interfere with context menus.
2. System File Corruption: Damaged Windows system files may impair core functionalities.
3. Registry Errors: Incorrect or corrupted registry entries related to file associations or context menus.
4. Antivirus Interference: Security software might block certain shell activities.
5. Recent Updates or Software Changes: New updates or installations can sometimes cause conflicts.

Step-by-Step Troubleshooting Guide

1. Restart Windows Explorer

• Open Task Manager (Ctrl + Shift + Esc).
• Locate and select “Windows Explorer.”
• Click “Restart” to refresh the process.
  Note: This often resolves minor glitches without a full reboot.

2. Run System File Checker (SFC)

System File Checker scans and repairs corrupted Windows files.

• Open Command Prompt as Administrator:

• Press Windows + X and select “Command Prompt (Admin)” or “Windows PowerShell (Admin).”

• Enter the command:

bash
sfc /scannow

• Wait for the process to complete. If issues are found and repaired, restart your computer.

3. Use Deployment Image Servicing and Management (DISM)

DISM helps fix component store corruption.
