Turn On or Off Start Menu AutoCascade of Submenus in Windows 10

Information
This tutorial will show you how to turn on or off to automatically open submenus in the
resizable Start menu when you pause on them with the mouse pointer for only your user account in
Windows 10.
This does not apply to the default
expandable Start menu.
When
turned off, you would need to click/tap on the submenu expansion arrow (caret) of a pinned item on the Start list to toggle it to expand open and close.
When
turned on, you can pause the mouse pointer over a pinned item on the Start list that has a submenu to have it expand open. You can still also click/tap on a submenu expansion arrow to toggle it to expand open and close.

Note
If you have turned off "Store and display recently opened items in the Start menu and the taskbar", then you will no longer have a submenu expansion arrow (caret) for some pinned items on your Start list.
For example, Notepad will no longer have a caret to expand open to show you a list of recently opened documents in Notepad.
