  • Staff

This tutorial will show you how to enable or disable launch folder windows in a separate explorer process by default for your account in Windows 10 and Windows 11.

Each process running in Windows is assigned a unique decimal number called the process ID (PID) to identify an active process. This number is used to specify the process when for example attaching a debugger to it.

By default, all File Explorer windows, including the desktop shell, run in a single explorer.exe process. If one File Explorer window hangs or crashes, it will cause all File Explorer windows running in the same process to hang or crash until the process restarts.

You are able to use the Open in new process context menu to manually open folder windows (File Explorer) in a new process.

If you like, you can enable to launch folder windows in a separate process by default. This way each explorer.exe process will have its own process ID (PID) to improve stability of the explorer shell.

Separate explorer processes appear to no longer work for the new File Explorer with tabs.

The article above shows explorer work as it should, and as it did in former windows versions. That however is not how it's working.

When I view explorer in Processes, every window is under one process.
When I view Details there are two processes that appear to be the desktop manager in one, and all the folder windows in another.

I have checked many times, the option is enabled. It's the first thing I do post-install.

When logged in as a standard user with admin rights. this remains the case however I launch a window (e.g. with cmd.exe).

If however I launch cmd.exe as Administrator and enter "explorer.exe" things work as they should. Given the risk that working as Administrator presents, that is not something I want to, or should, do.

Hello @leopardtail, and welcome. :alien:

I'm seeing the same thing with all explorer windows using the same process ID even with Launch folder windows in a separate process enabled.
