Windows 10: Where are my documents?

Just installed Windows 10.  I'm having a problem similar to a problem that I had when I installed Windows 8.

Documents seems to be in several tiers, including Public Documents, Documents, and so on.

There is one "Documents" that has just a few old folders and all the scanned documents that we've ever scanned (the scanner must put them there by default).

The other "Documents" has my actual library of many documents and document folders.

This is the "Documents" that I use and want to access.

I can find that whole set of documents in my administrator account, but not in the other account on my computer.

The other account only shows me the previous public documents from Windows 8.

The other account is the one that I use most. I want to be able to access all of my documents from that other account.

I've tried going into Users from the administrator account and sharing the (main, important) Documents folder with the other account so that I can access my documents when I'm in the other account.

Windows 10 assures me that the sharing is going on.

But when I go into the other account and click on Documents (both in Quick Access and in This PC), all I get is the former Public Documents with just the old folders and scanned documents.

What am I missing? Can you help me access all of my documents in both accounts on my computer?

Thank you!

(By the way, another issue I'm having with Windows 10 is that the Start menu does not show useful things, like Control Panel and My Computer, that Windows 8 showed. Instead, it shows a lot of bright tiles, frequent apps, and  few things at the bottom. Does anyone know how to customize the Start menu so it shows what I want it to show?

Thanks again!)
