Executors on Windows: Docker vs Docker-Windows

Reading the documentation for setting up the gitlab runner on Windows ( Install GitLab Runner on Windows | GitLab ) and the registration-on-windows documentation ( Registering runners | GitLab ), but here it says:

For most use cases, enter docker.

My questions then are:

  1. Does the default “docker” executor run both linux and windows containers?
  2. If not, can I configure both a docker and docker-windows runner on the same machine some how?
