I have no idea why my MDT scripts are running from the MDT deployment share (UNC) instead of the local copy.
Is it normal for %SCRIPTROOT% to point to the UNC of the MDT Deployment share? This is causing trouble for the removeapps powershell script. The PS script in offline mode looks like it assumes it is running from X: or another drive-lettered location and so I think it fails when it tries to list the path as $script:offlinepath, because that is null. That only gets assigned (lines 110 and 151) if the path starts with "<N>:" Can't figure out why my %SCRIPTROOT% is the UNC path instead of X:\something.

I remembered that MDT's "Extra files" copies the folder structure relative to the root of WinPE - so I was able to use ExtraFiles to get the .config file in the right spot. Now for testing the fix.

You give me the strength I need to make it through the day. I am trying to figure out a way to do this in a way that will survive MDT WinPE rebuilds (Update Deployment Share) I mounted the WinPE.wim at C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\en-us Injected the .config file and committed the change, but it didn't make it into the LiteTouch_x64.wim I'm not sure where I can stick that .config in a way that it will be incorporated. I know how to add the file to litetouch_x64.wim - it sucks that I would need to redo it after each update, but at least I know how. I am lost though on how I'd do the same to the ISO - which I need in order to boot the B&C VM... So I'll keep trying to figure out how to incorporate the .config file into the boot image so that it is there when I do an Update Deployment share...

The .config file has always worked for me, but either a lot of other people can't follow my instructions or they are having different results. Either way, I can't explain it. I had simplified the testing to eliminate MDT from the picture with a generic Windows PE boot image and then just manually ran "mshta.exe http://bing.com"; followed by PowerShell and "import-module DISM" and could reproduce the issue.

I have been reading a bit on this and can't figure out what the best way to correct this problem of DISM not loading correctly during MDT. Some say that that creating a .config file as Micahel's post suggests is not enough. Other blogs say you have to copy a DLL out of the WAIK toolkit. I see that the copy of Microsoft.Dism.PowerShell.dll included in the 1511 ADK at "Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Deployment Tools\amd64\DISM" has an MD5 hash of 31632e90280046d2efb020f7dcb23ab5 The copy of Microsoft.Dism.PowerShell.dll that gets installed by importing the DISM package into the WinPE image using the component import - and gets stored in the x64 WinPE.WIM at Windows\System32\WindowsPowerShell\v1.0\Modules\Dism is a different MD5 hash 71316d0f6f255f59efbe601f7dc33a58 The rest of the files in the WinPE Windows\System32\WindowsPowerShell\v1.0\Modules\Dism - the MD5 hash does match what is in the ADK. People mention that it works to copy the version of the DLL that is included in the ADK over the top of what is in the WinPE boot once the computer is booted into WinPE - so that leads me to believe there is a problem with DISM component that makes it import the incorrect copy of the DLL. The post Michael made about fixing this is from New Years Eve - so has there been any update on the best way to correct the DISM vs MSHTA problem? Not sure which thing to try... they are all kind of a pain to implement so I would like to fix it the best way first rather than try a bunch of things. I tried mounting my LiteTouch WIM and then copying the Microsoft.Dism.PowerShell.dll file from the ADK over the top of the one in the WinPE's WIM file but I'm getting access denied - it is owned by Trusted Installer. And even when I took owenership, I still couldn't delete or replace the file in the WIM and I tried lots of ways...
