Hi TB,
1. >It seems they are all in there, however many say 'Not reported yet'.
Please reset windows update components on the clients, check if it could work:

2. > At least show as Windows 10 devices now as I updated the server as before they said Vista.
This may due to you install KB3095113 on the WSUS server later, if we do not install this KB on WSUS server, win10 will show as vista;
3. >on previous OS's I could look in the c:\windows\Windowsupdae.log file for a clue, but that is gone on Windows 10.
