Windows Server 2012
Windows Server 2008 R2

So you are building a new image of Windows, and you want to deploy it to your environment.
You have been using unattend.txt/sysprep since Windows NT 4.0/2000/Server 2003 days or a 3rd party imaging software
And on Vista/Server 2008, you switched out to unattend.xml/syprep.
You passed by the Microsoft BDD (Business Desktop Deployment) toolkit.
That is alright, now you could save yourself time when building new systems (laptops, workstations or servers), and continue doing your other work by using the "Microsoft Deployment Toolkit”.
