I have made a autounattend.xml for the ground install that works fine. But when I try to import my regtweaks they are still missing after install. I have followed FireGeirer's guide, chapter: "HowTo: Importing Registry Tweaks during Vista setup". I can see during the audit mode that the reagtweaks.reg are find and imported. But when I reboot in oobe mode and log in as administrator they are missing. I have the regtweaks.reg on an USB-memory. Are there a way to do this in Windows 7 that differ from Vista?
