How to automate removing Windows Components

[Mordac85]

I'm trying to figure out a method to uninstall a few items that appear under Add/Remove Programs\Windows Components after a system has been built. I need to remove:

• Internet Gateway Device Discovery & Control Client
  
• Update Root Certificates
  
• Games (std & Internet)
  

I'm not sure if these are just registry entries or if there is something more complex. I've checked for system changes and found a number of these items listed in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\Oc Manager\Subcomponents, but I'm not real confident that it is the only point of change. I have a base image and need to adjust with a simple reg file or batch script until I can revise my initial build.
