After you update an unattend file that is already being used in imaging jobs the jobs don't use the updated unattend file.
When you create a job the current unattend file is saved into the Database. Changing the unattend file on the hard drive will not update the unattend file saved in the task. To utilize a new version of an unattend file you need to create a new task that uses that unattend file. An existing deploy image task will update the unattend file used when you choose an image.
