Steps to reproduce the behavior

  1. Install Windows Server 2016 Datacenter GUI as trial on Hyper-V (Windows 10)
  2. Winver is 1607 OS Build 14393.693
  3. Fully updated Server 2016 OS
  4. Ran “Install-Module -Name DockerMsftProvider -Repository PSGallery -Force” with success prior to docker install
