Which two possible files can you modify to achieve this…

You have the Windows Assessment and Deployment Kit (Windows ADK) installed.
You have a Windows Preinstallation Environment (Windows PE) image.
You copy a custom startup script to the image.
You need to ensure that the script runs each time the image starts.
Which two possible files can you modify to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

A.
Winbom.ini

B.
Unattend.xml

C.
Winpeshl.ini

D.
Copype.cmd

E.
Startnet.cmd

Explanation:
C: Add a Customized Script with Winpeshl.ini
You can launch a customized shell application by using a file called Winpeshl.ini. Winpeshl.exe will process the settings in Winpeshl.ini during boot. If you create a
customized Winpeshl.ini and require Plug and Play or network support, you must include a call to Wipeinit.exe. Wpeinit.exe specifically installs Plug and Play
devices, processes Unattend.xml settings, and loads network resources.
E: Add a Customized Script with Startnet.cmd
You can add customized command-line scripts in Windows PE by using Startnet.cmd. By default, Windows PE includes a Startnet.cmd script located at %
SYSTEMROOT%\\System32 of your customized Windows PE image. Startnet.cmd currently starts Wpeinit.exe. Wpeinit.exe specifically installs Plug and Play
devices, processes Unattend.xml settings, and loads network resources
* third way:
Add Customizations with Unattend.xml
You can use an answer file with Windows PE to specify various settings and actions. When Windows PE starts, it implicitly looks for a file called Unattend.xml at the
root of any bootable device (for example, a USB flash drive or a floppy disk). You can also specify an Unattend.xml file by using Startnet.cmd and Wpeinit.exe.
Note: The following procedure demonstrates how to add a customized script to a Windows PE image offline. Windows PE provides three methods for launching
custom scripts: Winpeshl.ini, Startnet.cmd, and Unattend.xml. The Windows PE default interface is a Command Prompt window. However, you can create a
customized Winpeshl.ini file to run your own shell application. You can also create your own version of Startnet.cmd to run a specific set of commands, batch files,
or scripts. Unattend.xml is a new answer file format for Windows PE 2.0, which replaces Winbom.ini and Winpeoem.sif.
