Over at TenForums, there are some instructions for toggling the Navigation Pane on and off, using the context (right-click) menu from within a folder
Though it involves a Registry edit, they provide the .reg files to download and apply. One adds the menu option, the other removes it if you decide you don’t want it after all.
Also, if you’re more venturesome, at Winaero there is a tool called “Ribbon Disabler for Windows 10 and Windows 8"
It disables the ribbon and puts the traditional menu in its place.
Though it doesn’t mention the Windows 10 Creator’s Update, it worked there for me. The author says it works for versions as late as the Windows 10 Anniversary Update.
Among other info, the author says:
“...Ribbon Disabler works by applying a resource hack to a Windows system file called “explorerframe.dll”. At the same time, it also creates a backup copy of the original dll, which it renames as “explorerframe.winaero”. This backup file is used by Ribbon Disabler in case you ever want to undo things & restore ribbon functionality...”
^^ That’s why I said “venturesome”. Resource hacks can be just a bit dicey, or so I found out with Windows 7. I don’t suppose it’s any different for Windows 8 or 10.
