Thanks for the suggestion Meyer, but even with twinui.dll and twinapi.dll there is no copy progress window.

I've had good luck with using Visual BCD Editor. http://www.boyans.net/

Have you managed to get the file copy-progress part of explorer working? With Win PE3 (Win7) it was as easy as copying shellstyle.dll, but there is more to it with this version. I would be content using a 3rd party file manager on my WinPE build, but I really would like Win8's file copy handling.
