On the taskbar I use quick launch and the pinning feature for quick access to programs. The good news is that quick launch is still there for Windows 10 and undoubtedly you will also still be able to pin programs to the taskbar.
I always put my taskbar on auto hide for more screen real estate
It is, but not by default, and the location requires some drilling. (Run shell:quick launch, or go to C:\Users\\username\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch
Place a shortcut to it in the Send To folder (Run shell:sendto, or drill to C:\Users\username\AppData\Roaming\Microsoft\Windows\SendTo, and send shortcuts to it.
MS seems to see users mostly as children who need big icons and need to be protected from self, and should not want to know things like file details, extensions, hidden files, or want much customization, and should not miss something like the Start Menu and Quick Launch bar, as instead they should just pin a dozen things to the Task Bar, if they even use a dozen things .
But i guess most people only use a PC for a few things.
