How to Enable Separate Process for Windows 11 File Explorer

Launch a File Explorer folder with a separate process

Running each folder in its own sandbox prevents a single crash from taking down the whole application. Configuration takes less than a minute through either the standard menu or the registry. Following these steps enables the Windows 11 File Explorer 📁 separate process feature for better stability.

The configuration process involves several specific actions.

1. Open the File Explorer 📁 Folder Options.
2. Click on the View tab.
3. Check the box next to “Launch folder windows in a separate process” to enable it. To disable it, uncheck the box.

4. Click OK to save your changes and exit.

Launch File Explorer window in a separate process using Windows Registry Editor

Power users can achieve the same result directly through the Windows Registry Editor database. Backing up registry settings beforehand remains a smart precaution. This method provides a technical route to achieve better File Explorer 📁 stability.

Backing up your registry or creating a System Restore point prevents potential issues before diving into the Registry Editor.

1. Open the Windows Registry and navigate to the folder key path below.
   

   Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced

   
   
2. Right-click Advanced > New > DWORD (32-bit) Value and name the new DWORD SeparateProcess.
3. ⚠️ ADMIN PRIVILEGES REQUIRED — Double-click SeparateProcess and change the value to 1 to enable launching windows in a separate process in File Explorer.
4. Enter 0 to disable the feature.

Applying the changes correctly sometimes requires a full computer restart.

That completes the setup process.

Summary

Turning on separate processes for Windows 11 File Explorer windows means if one window freezes, the others keep working, preventing the whole application from crashing. Each File Explorer window runs on its own, which means better stability and less chance of losing your work. This setting helps ensure that a single issue won't bring down all your open File Explorer windows.

What happens when done? Once applied, every folder operates independently. An unresponsive directory no longer brings down the rest of your desktop interface.

• Backup Precaution: Always back up your registry or create a System Restore point before making changes to the registry.
• Enhanced Stability: This feature can improve stability and responsiveness when navigating files and folders.
• Reboot Required: Changes may require a reboot, ensuring the settings are applied correctly.
