Post-Setup Windows updates

[Windows 10 User]

Can anyone tell me how to Post-Setup Windows updates? Before asking me why I want to do this since I simply could integrate them, read this. I noticed that NTLite automatically adds the parameter /quiet /norestart after I add one .MSU so I hope no windows show up after loging into my user account for the first time but if that happens how can I know if they were successfully installed, since the PC didn't restart (according to the command)? Can I have problems if after login on the user account I immediately search for updates when the install isn't complete and Windows Update detects the updates which are being installed and tries to install them? If I don't have internet access after I log in for the first time I suppose the updates aren't installed.

EDIT: The Windows 10 1803 build number didn't change so the install failed. What is the right parameter? I used the KB4343669 (filename: windows10.0-kb4343669-x64_2a58320e44d3ff803bc7016b5d02f3e85482b46f) and KB4345421 (filename: windows10.0-kb4345421-x64_c5a035dc1ec030a5be0626c8b019b9c4f6e8a1a6) .MSU files.

As you already saw you can just add them to Post-setup, they will be executed silently before any user logon.
Post-setup progress UI not implemented yet.
I recommend to reboot after the first login, or integrate, which we can discuss on the other topic.

If they are executed before any user logon then why is it recommended to reboot after the first login? Windows 10 successfully installed after I rebooted but in that case why are these commands (/quit /norestart) needed since the install only happens if I restart the PC?

Also, they may be installed by Windows Update if I search for updates so I have to remember to not search for them but if I forget and it says that the PC must be rebooted will it interfere with the Post-Setup updates that are precisely installed after the PC is rebooted? If I don't have any problems installing updates through Windows Update if I don't integrate updates then it doesn't make much sense to Post-Setup the updates.
