If You Use $OEM$ and MDT 2012, Some Things You Need to Know
Michael Niehaus has a post up about some changes in MDT 2012 that effect the behavior of the $OEM$ method. I’ve had a few posts on $OEM$ in the past, and you find those here.
I mentioned in the blog post at http://blogs.technet.com/b/mniehaus/archive/2012/07/21/mdt-2012-update-1-always-applying-images-with-imagex.aspx that MDT 2012 Update 1 no longer uses SETUP.EXE to install Windows 7 and above. One side effect of this is that $OEM$ folders are no longer going to be copied, since that was something that SETUP.EXE did that the MDT LTIApply.wsf script doesn’t handle.
I’ve never been a big fan of using the $OEM$ folder structure, as it’s just as easy to add explicit XCOPY steps into the task sequence. But for those of you out there that are using them, you can leverage the attached script (see the attachment link below) in your task sequence to do that.
