I know it's frustrating to not get a step by step answer but most of what you need to know has been explained numerous times and the answers are out there. Here's something to get you started.
There are several ways to do what you want to do. Here's the easiest way I can think of. It's untested, but simple enough that it should work without any problems.
First, open Notepad and type the name of each switchless installer you want to include. Enclose each in double quotes and put one file name on each line. For example:
"Program1.exe"
"Program2.exe"
etc.
Save the file as Installers.cmd
Next, create a folder named Installers and copy the switchless installer files into that folder. Also copy the Installers.cmd file you just created into that same folder.
Now, you have a folder that contains all of your switchless installers as well as a program (the cmd file) that will install each of them when it is run.
If you have a virtual computer program or a test computer to work with, you can copy the Installers folder to that machine and run the cmd file to make sure everything works as expected.Use nLite as you have been doing to create the unattended compilation. When you get to the Unattended section, look for the RunOnce tab. There, you can enter the command(s) you want to run after the first time Windows logs you on near the end of the installation. Enter this line:
CODE
%SystemDrive%\Installers\Installers.cmd
Continue with the nLite process until you get to the Bootable ISO page. Stop there without making the ISO image, but leave nLite open.
Locate the $OEM$ folder in your set of unattended installation files. In that folder, you may find a folder named $1. If not, create a folder named $1 inside of the $OEM$ folder. Open the $1 folder and drag the folder you created earlier (Installers) into the $1 folder.
Everything in $1 will end up on the drive where Windows gets installed (probably C:), so you'll later see a folder named Installers in the root of that drive. This process doesn't cleanup after itself, so you'll want to delete that folder when everything is done.Go back to nLite and continue with making the ISO image.
During installation, Windows will run Installers.cmd at first logon.
That should do it. There are a lot of ways to enhance and cleanup this process. For that, I suggest searching the site and also checking out the Unattended Windows Guide 0d recommended if you haven't done that already.
Good luck.
