In-place upgrade parameters are not working to upgrade Windows 10 to Windows 11 ( 23h2 )

Question

Hello,

the idea is to use the in-place upgrade from windows 10 to windows 11, however, it looks like the new ISO 23h2 the parameters are not working.

Here are the steps we are following:

1. download the iso from Microsoft
2. mount the ISO
3. run the script with parameters.

I'm using a similar code from here to download and mount the ISO and run the setup:

• https://github.com/CakeRepository/install-windows11

These are the arguments to give to the Windows 11 setup.exe after it is mounted.

• https://learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/windows-setup-command-line-options?view=windows-11

The Errors:An unknown command-line option [/quietinstall] was specified.

Answer 1

Hello,

I consider that the /quietinstall switch is not a recognized parameter for the Windows 11 setup. The error you are receiving indicates that the command-line does not understand the /quietinstall parameter.

You could try to run a quiet install with an ISO in Windows setup would be /quiet. Meaning your script should look like "path to setup.exe" /auto upgrade /quiet. This will perform the upgrade in quiet mode which will not interact with the desktop and will not restart the computer after the installation.
