Unattended Windows 10 Installation

Windows10 Autounattend

This project is optimized for installation via an USB stick. All available Windows updates and Manufacturer specific drivers for Lenovo are installed automatically. Also various software packages can be installed automatically via chocolatey. They default account after the installation is DeviceAdmin with the password password*

Create an USB Boot Device

To create a bootable USB stick I recommend one of the following tools. Ventoy has the advantage that several ISOs are available at the same time on a USB stick.

• Use Ventoy with the Auto Installation Plugin
• Use this Powershell script from VMware

If the error dialog is displayed after the installation and the computer hangs in a loop after confirming, this can be fixed with this trick.

1. When message appears, press SHIFT + F10 to open CMD
2. Type: regedit.exe
3. Browse to HKLM/SYSTEM/SETUP/STATUS/ChildCompletion in setup.exe, change the value from 1 to 3.
