Windows server 2003 How to install updates correctly?

Question

Windows

Hello, I installed windows server 2003 and started manually installing updates wuauclt.exe /detectnow.
I receive updates in portions of 3-4 pieces, then a reboot is required. I haven't waited for all the updates to install yet, but I've already done ~20 reboots. Is there a way to automatically install 50-100 updates at a time?
I want something like apt-get update && apt-get upgrade, and mind my own business

Answer 1

So install the latest version, with the latest service packs.
And so, this is quite normal. First, the update installer is updated, then critical updates, etc., etc. Windows - get used to it.
Anyway, support for Windows Server 2003 will end on July 14, 2015. Maybe it makes sense to put the OS fresher?

Answer 2

Come IE from the server on www.update.microsoft.com
Further - all in Russian. There will be 1-2 reboots, but not 20 at all.
Or turn on Automatic Updates in the Control Panel. The server will do everything
