Another approach is to edit launch shortut


ShortCut is located here
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Octave-4.2.1


Copy CLI or GUI shortcut and paste where you like.
Right click icon of shortucut and show 'Property' tab
Edit the Working Folder where you like and [OK].

Use the custermized shortcut.

If  Working Folder is empty, working folder is set to the folder where shortcut 
is located.
