I’ve been working with MDT 2012 in my test environment, and here are three new features that I really like.
Dirty Environment Cleanup
Some times a deployment fails from some reason, and you just want to restart the process of a bare metal install. In MDT 2010, the task sequence would read the logs written to the hard drive and realize that a deployment was still in progress. At this point, MDT 2010 will halt the process with an error. Pressing F8 and using diskpart to wipe the disk is my usual work around, but it is a bit clumsy for less experienced technicians.
