Windows 10 problems

I have a newly acquired laptop with Windows 10, Version 1511, Build 10586.545 installed and activated. When I ran Windows Update, it said the following 9 updates were available:
-Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3185614)
-Windows Malicious Software Removal Tool for Windows 8, 8.1, 10 and Windows Server 2012, 2012 R2 x64 Edition - September 2016 (KB890830)
-Update for Windows 10 Version 1511 for x64-based Systems (KB3161102)
-Update for Windows 10 Version 1511 for x64-based Systems (KB3181403)
-Security Update for Adobe Flash Player for Windows 10 Version 1511 for x64-based Systems (KB3188128)
-Synaptics - Pointing Drawing - Synaptics PS/2 Port TouchPad
-Security Update for Windows 10 Version 1511 for x64-based Systems (KB3172729)
-Update for Windows 10 Version 1511 for x64-based Systems (KB3152599)
-Western Digital Technologies - Other hardware - WD SES Device
So, I disconnected the laptop from the Internet (because I have a metered Ethernet connection), and ran WSUSOffline updateinstaller.exe to install the updates that I downloaded from another machine. After going through the update procedure for about 30 minutes, WSUSOffline updateinstaller.exe completed and told me to reboot. When I then ran WU, it showed the same 9 updates available!
I realize that some of these updates are blacklisted or not in the update catalog, but why are the cumulative updates not present? Is this because I have version 1511 instead of the Anniversary edition? Or?
I also note that the "automatic reboot" function doesn't seem to work properly, as I have to log on and restart updateinstaller.exe every time it reboots. Unless this means that it was through updating???
I seem to recall that updateinstaller.exe would display a message saying "Nothing to do...." when it was completed, rather than just "please reboot"? The latter implies that it isn't complete?
