I have a Windows 10 machine configured the way I need. all windows are closed only thing available are the shortcuts on the desktop.
I copy a unattend.xlm file to c:\windows\panther
I open a command prompt change to c:\windows\system32\sysprep and execute sysprep /generalize /oobe /shutdown.
Process is successful.
When I power this machine back on it goes thru the boot process as expected and after all reboots are completed the desktop appears but a File Explorer window opens as well.
I cannot find why this file explorer window now opens every time the machine is rebooted.
I checked things like startup and runonce registry keys.
Any help is appreciated
