Fix Duplicate Drives in Windows 10 File Explorer Navigation Pane

If you’re noticing that your drives are appearing twice in the File Explorer navigation pane on Windows 10, it can be confusing and clutter your view. This issue may be caused by system glitches, registry errors, or drive letter conflicts. Fixing it helps restore a clean, organized navigation pane, making your file management smoother and more intuitive. Before you start, ensure you have administrator access on your computer, as some steps involve editing system settings or the registry. It’s also recommended to back up your registry or create a system restore point to prevent potential data loss or system issues.

What You’ll Need

• Administrator access to your Windows 10 PC
• Basic understanding of Windows File Explorer
• Optional: Backup or restore point (recommended)

Step-by-Step

1. Close all open File Explorer windows. To ensure changes are applied correctly, close any open File Explorer sessions.
2. Open the Registry Editor:
   • Press Windows key + R to open the Run dialog box.
   • Type regedit and press Enter. Confirm any User Account Control prompts to allow access.
3. Navigate to the following registry key:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\MyComputer\NameSpace

4. Look for duplicate entries:
   • In the left pane, review the subkeys under the NameSpace key.
   • Identify entries that correspond to your drives. Usually, each drive has a unique CLSID or a known name.
   • If you see duplicate entries for the same drive, select one to delete.
5. To delete a duplicate entry:
   • Right-click on the duplicate key.
   • Select Delete.
   • Confirm the deletion when prompted.
6. Refresh the registry:
   • Close the Registry Editor.
   • Press Windows key + R, type explorer.exe, and press Enter to restart File Explorer.
7. Check if the drives no longer appear twice:
   • Open File Explorer and look at the navigation pane.
   • The duplicate entries should be gone, leaving only one instance of each drive.
8. If the problem persists, consider using a third-party tool like CCleaner to fix registry issues or perform a system file check:
   • Open Command Prompt as administrator.
   • Type sfc /scannow and press Enter.
   • Allow the scan to complete and follow any instructions provided.

Common Mistakes

• Deleting the wrong registry keys, which can cause system instability.
• Not backing up the registry before making changes.
• Forgetting to restart File Explorer after editing the registry.
• Ignoring drive letter conflicts that might cause duplication.
• Using registry cleaners that can sometimes remove necessary entries.

Tips

• Always back up the registry before making edits: In the Registry Editor, go to File > Export, and save a copy.
• Use the built-in System File Checker (sfc /scannow) to repair corrupted system files that might cause display issues.
• Ensure your drives are properly assigned and not conflicting with network drives or mounted volumes.
• If you’re unsure about deleting registry keys, seek professional help or consult online forums.
• Regularly update Windows 10 to benefit from bug fixes and improvements that might resolve such issues automatically.

Troubleshooting

If the duplicate drives still appear after following the steps above, try these additional fixes:

• Perform a system restart: Sometimes, a simple reboot refreshes the system and clears temporary glitches.
• Check for drive conflicts:
  • Open Disk Management by pressing Windows key + X and selecting Disk Management.
  • Ensure no drives have overlapping drive letters or mount points.
• Reset the navigation pane:
  • Open Command Prompt as administrator.
  • Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter. Wait for the process to complete.
  • Follow with sfc /scannow as described earlier.
• Check for Windows updates: Outdated system files can cause display issues. Go to Settings > Update & Security > Windows Update and install available updates.
• If none of these steps work, consider creating a new user profile to see if the issue is profile-specific or performing a system restore to revert to a previous state where the drives appeared correctly.
