Insider Preview 17723: docker pull does not work without Hyper-V feature installed

I came across this thread and wanted to follow up with more information as I have confirmed the information with the Product Group. This issue has been fixed in later builds. 

The only dll needed, which is missing since Hyper-V role is not installed, its vmwpctrl.dll.

 If this is a physical system:

1. install the Hyper-V role and this will install the missing .dll
2. Restart
3. Uninstall the Hyper-V role, if the role is not needed.

If the container host is a Hyper-V VM

1. Shut down the VM to https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/user-guide/nested-virtualization
2. Install the Hyper-V role and this will install the missing .dll
3. Restart
4. Uninstall they Hyper-V role
5. Restart
