Use autounattend.xml files to install Windows 10/11

Windows Setup will automatically search for autounattend.xml files at various locations, including the root folders of each removable drive. Therefore, you do not need any third-party software, and you do not need to modify .iso or .wim files. Just follow these steps:

To install Windows from a DVD

1. Fill out the form, then click the Download .xml file button.
2. Copy the autounattend.xml file to the root folder of a USB drive and connect it to the computer.
3. Boot from the DVD drive to begin the unattended installation.

To install Windows from a USB drive

1. Fill out the form, then click the Download .xml file button.
2. Copy the autounattend.xml file to the root folder of the USB drive that contains the Windows Setup files and connect it to the computer. (The autounattend.xml file will be located in the same folder as setup.exe.)
3. Boot from the USB drive to begin the unattended installation.
