Need some clarification about WSUS server

After reading lots of articles I need still clarification about some basic facts:

At first: There is a "normal" built-in Windows Updates service available in ALL Win10 versions.

Beside this "basic" update mechanism there is a so called "WSUS" service.
This is a separate (software) server which handles all Windows Updates for all Windows computers of a company. These depending Windows computers retrieve their Updates not by the built-in Windows Update service but from the inhouse WSUS server.

A WSUS is running on a separate Windows computer which MUST have a Server or Enterprise Edition.

A WSUS Server can NOT be installed (afterwards) on a Windows Pro or Windows Home Computer

Correct so far?

Can depending Win (Pro/Home) computers in LAN decide on demand whether they retrieve Updates from WSUS server OR by themselve? or is it an always-WSUS-server-or-never?

Does the WSUS server architecture described above apply to Windows 7 networks as well?

Do Windows 7 Pro/Home computers work with WSUS servers on Win10 servers as well?

Thank you for confirmation and comments

WSUS is a Windows server role so yes it will only be on a Windows server edition. All Windows computers, provided they are Pro or Enterprise or Education can use GPO to redirect to a WSUS server for updates. In smaller businesses with WSUS only you can use additional GPOs and computer groups to manage which systems get what updates and when.

WSUS is the service... it runs on a server and gets its updates from Microsoft then other computer log into that server to collect their updates
the point is that these computers are not going to the internet {and therefore Microsoft} themselves and you can control which updates are used i.e, filter out the busted ones

anyone can run a update server on Hyper-v (which is free) and you don't need a GPO but that is the normal way... computers can get their updates from Microsoft and the local WSUS (they are both the same updates) but only WSUS can be filtered before download... if you get updates dirrect from Microsoft you can uninstall them again and you can decide that you don't want any updates but only a WSUS allows you pick which updates to install per system so for example the W7 computer may not want sp2 because it breaks their printer drivers

yes home and pro can both use a WSUS but most people think its only Pro because Home doesn't really use GPO which as we said is the normal system

WSUS for Windows 7 will need extra work to set up because Windows 10 uses a different network system... in practice most people keep Windows 7 computers on a different network to Windows 10 so that Windows 10 doesn't bugger up your 7 network but it is possile to run them together i.e, WSUS for XP Vista and 7 then a different W10 Wsus is better than one WSUS for everyone

While technically true you can point Home editions at WSUS it's not really done typically. Also there really is no reason to segregate Window 10 from other OSes. The Windows 10 update sharing feature can cause some network congestion but it's minimal and even most home switches can handle it without any difficulty.

its a senario that happens a lot when Windows 7 people first start playing in Windows 10 networks... sud printers and what not stop talking to the network
to be clear, yes a well made network can run Windows 10 with Windows 7 etc but its the same as running Mac and Windows together... most people avoid it after the first major crash
