This update process takes a while (an hour or so per batch file). ------------- If it does not take a while, then something went wrong.

You will have to reboot your server, delete all files in C:\WinPEmnt and attempt to unmount any WIMs that were mounted there. Run the following command to unmount at that location if you need to retry: "C:\Program Files (x86)\Windows Kits\8.1\Assessment and Deployment Kit\Deployment Tools\amd64\DISM\"Dism.exe /Unmount-Image /MountDir:"C:\WinPEmnt" /discard You may want to edit the batch files and add a pause at the end to see where the failure points are. -------------
