Unattended Windows 10/11 Install with autounattend.xml

1. Go to the Schneegans unattend generator and choose your options (language, edition, local user, bypass TPM/network checks, remove bloatware...). Download the file as autounattend.xml.
2. Create a Windows installation USB (Media Creation Tool or Rufus).
3. Copy autounattend.xml to the root of the USB.
4. Boot from the USB: setup finds the file and runs on its own.

Careful: if you let the file partition the disk, it will wipe it without asking. Test it in a VM first.
