in Autounattend.xml try to remove all part containt your local account, and admin password (just for test if unattended install works) and try to change all entry like that: <InputLocale>0409:00000409</InputLocale> by <InputLocale>en-US</InputLocale> win7 allow it but i think the better way for install apps, is install W7 non unattended, at the first boot in OOBE pres ctrl+shift+F3 to enter in audit mode and install all your apps (!!! never close sysprep windows in audit mode!!!) you can safely reboot if it's needed. when all apps are installed go to "%windir%\panther\" check in unattented.xml at "setting pass" line and remove: wasPassProcessed="true" after the pass name. then kill "wmpnetwk" in taskmanager and sysprep /generalize /oobe /reboot (or stop) and capture image offline sorry for my very bad english
