Windows updates for Windows 2008 Core

You can use Windows Update to patch Server Core, but you first need to turn it one using the following commands:

Cscript c:\windows\system32\scregedit.wsf /au 4

Net stop wuauserv

Net start wuauserv

This will use the default time of 3am to check for patches. If you want to force an update check, you can run:

Wuauclt /detectnow
