Did you know that you can download *.iso images of Windows 10 using the Get Windows 10 app?
It’s a tool that will allow you to download *.iso images for deployment.
The only problem is that it doesn’t actually download *.iso images, instead, it downloads *.esd images, which are highly compressed *.wim files, that are encrypted/encoded. The tool then decrypts/decodes the *.esd file into *.wim files, and constructs a *.iso image for use.
Additionally, the *.wim file is still a highly compressed *.esd file, so legacy tools that leverage the WIMGAPI library like imagex.exe don’t understand it. Dism works fine.

That means that you can’t import the images into MDT, because MDT uses the WIMGAPI libarary, and powershell commands might not work either.
I tried to export the *.wim file to another *.wim file, but DISM.exe doesn’t like doing that either.
As a work around you might be able to export the *.wim file to a *.vhd container, and re-capture back to *.wim file with normal compression.
Johan has been documenting esd to wim techniques on his blog.
Otherwise, I hope the DISM team fixes this for TH2 :^) <hint> <hint>
