Windows 11 file explorer extensions common issues

  • Extensions still hidden after enabling the setting: Clear the File Explorer cache by opening Task Manager, ending the “Windows Explorer” process, then restarting it through File > Run new task > explorer.exe to refresh the display settings completely.
  • Setting doesn’t persist across folders or restarts: Verify that you’re modifying the global Folder Options rather than individual folder properties, and ensure you have sufficient administrative privileges to make system-wide changes that affect all user accounts.
  • Some file types still don’t show extensions: Certain system files and Windows-protected file types remain hidden regardless of your settings for security purposes, and you may need to enable “Show hidden files” in Folder Options to view these protected system extensions.
  • Registry changes don’t take effect immediately: After modifying registry values for extension display, you must restart the Windows Explorer process or sign out and back into your user account for the changes to propagate throughout the system interface properly.
