Creating a Custom OS Installation?

I am currently running a windows xp computer that i have put a lot of time and effort into to make it just the way i like it. I have several registry tweaks, visual customizations, and programs installed which allow it to be the perfect environment for its purpose. I have three other computers, different makes and models, that i would like to be exactly the same. As these are work computers, i want to have them up and running asap. Is there a way to make a windows disk that can install all of those objects during the initial os installation? ume i have an original xp disk, all the installers for the applications, and i know how to recreate all of the hacks and tweaks. If this is not an option, is there a way to make a post installation disk that can easily enact the same idea? eg: after windows is installed, it will run all of the installers, hacks, and modifications from one disk or disk image with a single click. If none of the above are possible, and other ideas would be great. Thanks ahead of time.
