I have recently upgraded to MDT 2012 update 1 and Windows ADK (I have removed AIK as I believe I no longer need it). I have noticed that the "Create WIM" task is taking at least twice as long to create the WIM file when compared to before the upgrade
when I was running MDT 2012 with Windows AIK 3.0. This is exactly the same Windows 7 build that I am creating but the time taken to create the WIM has doubled from approximately 30 mins to 60 mins.
My usual trick to speed this proccess up before in previous MDT updates was to edit ZTIBackup.wsf in the Scripts folder in the Deployment Share and change the /compress maximum to /compress fast. This always used to make a big difference. However
this time it has had no effect.
