There is a proxy involved in my environment which is correctly configured for Docker Desktop (without that the response to command was that authentication is required).
Issue command: docker pull-hello-world.

: x509: certificate signed by unknown authority (possibly because of “crypto/rsa: verification error” while trying to verify candidate authority certificate “MyCompany WebGateway CA”)
Starting with Docker Desktop for Windows 1.12.1, 2016-09-16 (Stable) and Beta 26 (2016-09-14 1.12.1-beta26), all trusted Certificate Authorities (CA) (root or intermediate) are supported. Docker recognizes certs stored under Trust Root Certification Authorities or Intermediate Certification Authorities.
This doesn’t appear to be the case as I have verified that proxy certificates are both in Root and Intermediate locations.
Googling on this error I have found a lot of information but, sadly, none of it seems relevant to my case.
