I love Windows Server 2008 installed with Server Core. It’s small footprint (although it could be even smaller), simplistic command line UI, and the boot speed. One thing I dislike (until recently) is installing updates on Server Core. Well I found a nice little sample script that works beautifully to check and install all available updates from the command line
This is a VBScript that uses the built in Windows Update Agent (WUA) to check for all available updates, provide you a list, and allow you to select to download and install the updates on your machine.
This makes updating a Server Core image a breeze.
