Please let me know my understanding is correct or wrong regarding OSD deployment scenario is UDIWizard_config.xml file and Windows system image manager (customsettings.ini) UDIWizard provides rich user interface and option for language selection. Disadvantage is need to create variable to automate the OSD process.
Customsettings.ini all settings are automated only thing is OS language selection user need to select so respective language will install
