Remove cluster aware updating

As failover clusters are all about high availability of services hosted on the cluster, one would almost never patch all cluster nodes at the same time.

This hotfix plug-in can also be customized to apply non-Microsoft driver, firmware, and BIOS updates. If the cumulative updates are general distribution release updates or LDR updates, CAU can apply them. CAU supports the following updating modes, both of which allow updates to be scheduled: Self-updating Enables the cluster to update itself according to a defined profile and a regular schedule, such as during a monthly maintenance window.

You can also start a Self-Updating Run on demand at any time.

The main challenge with Server Core in Windows Server 2008 R2 and Server 2008 is that Server Core has to be set at installation time and can't be changed without reinstallation.

This is a big risk for organizations not used to managing Windows Server from a command prompt or remotely.

In a Server Core environment, the graphical interface, management tools, and management infrastructure are removed from the Windows deployment.

This typically means about 50 percent fewer patches and, more important, longer times between reboots, because the patches that are no longer required are typically those that require reboots.Addressing this was always the #1 ask for Windows Server 2012, during all the discusssions we had with customers in early days of release planning.Cluster-Aware Updating (CAU) is an exciting new feature that we have added in Windows Server 2012 that addresses precisely this gap.In addition, in Server 2008 R2 and Server 2008, Server Core is supported for only infrastructure roles (i.e., roles that are part of Windows Server itself) and not for other applications. Server Core is now the default installation option for Server 2012.The graphical interface, management tools, and management infrastructure can now be added and removed at any point in a server's life cycle, with only a reboot required.O yeahh, you don’t even have to start the patching by hand, you can schedule it to run automatically.
