I know how install software using a combination of .msi package and group policy. What I want to know how can I apply it in the real world when dealing with windows update. If have a thousand computers in my company i don't want to go to very machine a run windows update, all I need to do is to download those update and use group policy to install it when every machine boots up.
My question is: where can I download those packages?
I also know about the new windows automatic updates that one's can configure it to download the updates and install automatically with windows scheduled tasks.
