If there is some damage to the OS or account where the desktop is not working correctly, then the first time Explorer is run your desktop and such will open. On the second run then you get a Windows File Explorer instance or window.
You mention eShell which I would have to google but if eShell replaced the desktop, then Windows would again do as I noted.
I see no bug or unexpected operation here.
Hello everyone i have a problem.
After a user automatically logs in he get this screen, after that he needs to access some of the files, so he opens the task manager with keyboard shortcut ctrl + shift +e and goes to new task. In the pop up window he needs to input explorer so he could open the file manager, but instead he gets whole explorer opened with desktop and evrything else.
