To have separate processes for each File Explorer window, follow these steps:
- Search for and launch "File Explorer Options".
- In the dialog that appears, open the "View" tab.
- Select the "Launch folder windows in a separate process" option.
- and click "Apply" and "OK" to confirm the change.
Applies to all versions of Windows 10
File Explorer, which runs through "explorer.exe", is one of the most commonly used components of Windows.
Explorer.exe has two distinct roles: displaying some basic UI elements such as the taskbar and providing a graphical file management interface.
By default, both of these roles are performed by a single "explorer.exe" process. So in case an item encounters a problem, both functions of Explorer have an error. It may have happened to you when a File Explorer error resulted in the instantaneous loss of the taskbar and desktop icons. Windows then automatically restarts Explorer, resetting the interface.
With the above steps you can isolate the two key components of Explorer, forcing the browser windows to run in separate processes.
Since version 1903 of Windows 10, this setting is said to be enabled by default. But in all the systems we have been looking for, it is not always. It is worth checking if it is enabled on your Windows 10 device.
Once enabled, File Explorer windows will open in their own process and an error will not affect the disappearance of the taskbar.
