Windows 10 uses drivers direct from the manufacturers including their software suites if available.
eg. updating intel gfx drivers will also install Intel HD Graphics tray software
From personal experience, others also include AMD Catalyst Suite, Realtek HD Audio tray, Conexant Dolby Atmos and Smartaudio HD software.
They will be installed if u connected to LAN during Windows installation or updating drivers.
When I installed Windows, I only needed to install my RAZER Synapse additionally, rest of the software suites was auto installed from windows update. My guess is RAZER Synapse needs to login.
I've already installed Windows 10 on 5 different PC/laptops/tablets at home, and it was the same for all of them.
