Error in Docker for Windows tutorial

I'm new to Docker so I don't even know where to look. Here are the instructions:

Next, pull a base image that’s compatible with the evaluation build, re-tag it and to a test-run:

docker pull microsoft/windowsservercore:10.0.14393.321
docker tag microsoft/windowsservercore:10.0.14393.321 microsoft/windowsservercore
docker run microsoft/windowsservercore hostname
69c7de26ea48

And this is the error I get on the docker run step:

docker: Error response from daemon: container 6abd92755a8d5d13463eb74f9cc39a798ad0ec898bc1f80ff71205235b63a94f encountered an error during CreateContainer: failure in a Windows system call: No hypervisor is present on this system.
