CAU runs in two completely different modes, and the distinctions are important.

The first I’m going to talk about is called “remote-updating mode” in the official documentation.

You can find a full walk-through for enabling CAU on Tech Net: Now that the groundwork is laid, you can start with CAU.

As with most things Microsoft these days, you can choose between a GUI or Power Shell.

Whether your servers have a multi-continental presence or have been relegated to a closet, there’s never enough staff allocated with enough time to manually manage these systems.

Even if you did have the time, why would you want to?

In today’s data center, and for the foreseeable future, the biggest word is “automation”.

It doesn’t matter how big your datacenter is, either.The Power Shell cmdlet ( The other mode is self-updating. The very last text field, the one that shows the Power Shell script, is selectable.

Set this screen as close as you can and continue on. There is a link at the top that explains some of them to some degree. I’d go ahead and let the GUI set everything up initially, though. You can use it to repeat the installation for other systems without spending all that time in the GUI. Want to change Any errors at any point halt the entire process. It will even detect if an updating run would cause a cluster to dip below quorum, and won’t run if that’s the case. One thing you definitely don’t want to do is set up Windows Update on the nodes.You only need to enter proxy information if your hosts can’t connect directly to a WSUS system or Microsoft’s Internet-based update servers.If you have any errors on any outputs and need to know what to do, the Microsoft link above shows a table of solutions.If you don’t want to drill down that far, Read and Create all child objects will cover it.
