The ServerGuide Scripting Toolkit provides a sample unattend.txt file for each supported version of Microsoft Windows.
The answer files are located in the SGTKWinPE\AnswerFiles directory.
By default, the TK_NOS_AnswerFile variable in the SGTKWinPE settings .ini files is set to point to one of these sample files. If you are going to use one of these sample files by default during the deployment step, be sure to customize the correct file before starting a deployment. Specifically, if the version of Windows being deployed requires a product ID key, then this key must be provided in the scenario .ini file or the deployment will stop and prompt for this information.
