Many people are finding that choosing shutdown options in Windows 10 is made easier by use of the shortcut next to the name of the account at the top of the Start Menu.
But I still like to add a direct "Shutdown" item to my Start Menu:
1. Create a new shortcut on the Desktop to:
%windir%\System32\shutdown.exe /s /t 0
(that is a 'zero' at the end)
2. Change the icon as desired, and create a shortcut key if desired.
3. Drag to Start Menu.
NOTE: After your new item is in the Start Menu, you may also drag it from there to create a tile. Resize as needed.
