I have a simple Dockerfile:
FROM mcr.microsoft.com/windows:1809
# Install chocolatey
RUN powershell.exe Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))
# Install cygwin
RUN choco install -y cygwin --version 3.1.2
RUN refreshenv
CMD [ "powershell" ]
The result is
PS C:\vagrant\delme> docker build . -t localhost/async_windows_service

I tried different version of cygwin, also modified the storage size, as suggested e.g. here.
It is strange. The installation seems to go fine but docker cannot find the file (a layer I suppose) with path="\\\\?\\C:\\ProgramData\\docker\\windowsfilter\\eeae1d5f886b0b035f4466cf124056f7c1924283548cd960e0024a33d1219984"
And indeed, in my C:\ProgramData\docker\windowsfilter directory, there is no folder starting with eeae1d...
Note that only cygwin is causing problems. I can install all kinds of other software.
It seems that it is hardlinks which Cygwin uses a lot are not handled correctly by Docker. And in particular when Docker tries to commit an image it fails with "hcsshim::ImportLayer - cannot find the path" error.
I run in the same problem recently and after I got rid of the hardlinks in Cygwin installation I was able to commit the image without problems.
To get rid of the hardlinks I have zipped and unzipped Cygwin folder.
