Inplace unattended install?

[Grid21]

Would it be possible to have an version of Windows 11 upgrade that is for "inplace upgrade" using an unattended.xml file? I've been trying to find information about it on Google and haven't turned up a lot that makes it simpler to do. I'd be happy to help test it in a VM, inplace upgrading from Windows 10 to 11 using an unattended, I am not just not knownledgable yet enough to know how to do it myself. Let me know and thanks!

I asked ChatGPT how you can do this. I am not able to test it right now but you are free to test it yourself.

To use an unattended.xml file for an in-place upgrade from Windows 10 to Windows 11, you need to follow these steps:

1. Prepare the Windows 11 Installation Media:

   • Download the Windows 11 ISO file from the official Microsoft website.
   • Create a bootable USB drive or extract the contents of the ISO to a folder on your computer.

2. Update the Unattended XML File:

   • Ensure that your unattended.xml file is configured correctly for Windows 11. There might be new or different settings required compared to Windows 10.
   • Make any necessary modifications to the file to account for changes in Windows 11. You might need to refer to the official Microsoft documentation for the specific settings applicable to Windows 11.

3. Place the Unattended XML File:

   • Copy the unattended.xml file to the sources folder of your Windows 11 installation media. The path should be: path-to-windows-11-media\sources\unattend.xml.

4. Run the Upgrade:

   • Open a Command Prompt with administrative privileges.

   • Navigate to the folder containing the Windows 11 installation files.

   • Run the setup with the following command:

     setup.exe /auto upgrade /unattend:path-to-unattend.xml

Replace path-to-unattend.xml with the actual path to your unattended.xml file if it is not in the sources folder.

This command will start the in-place upgrade process using the settings specified in the unattended.xml file.

Cool! I will try this in a VM and let you know the results! This project for doing unattended installs is SUPER cool and I am ALL HERE for it! So if I can test stuff for the project in a VM that's fine with me!

Tes Results came back, my full command line was E:>setup.exe /Auto:Upgrade /unattend:E:\sources\unattend.xml Windows 10 replied with error "An Unknown command-line option [/Auto:Upgrade] was specified. Apparently this wasn't correct so I am confused why ChatGPT thought that was the correct command.

EDIT: turns out the correct command was this: setup.exe /unattend:E:\sources\unattend.xml. Rerunning the tests now with a custom unattend file.

Updated EDIT: The command worked, but unfornately, doing the upgrade ends up wiping the computer clean, instead of keep existing user and program data. So what can be done on the website that lets you customize your xml to keep your data intact?
