I'm new to using Win Toolkit, but I've got a general question related to the continued updating of a build over time. I know that I can take a WIM that I've updated with Microsoft updates and add additional Microsoft updates as new updates are released. However, let's say that I'm also integrating a few addons or silent installers (runonce). What is the proper method to remove and/or update addons or runonce installers in a build? Do I have to start from scratch to do this? If so, that would be a real pain to have to integrate all the updates again just to modify an addon. Any recommendations or instructions would be greatly appreciated.
