Has Drone given up on Windows containers?

Nope, we were just working on another side of windows support. We have just released the alpha of GitHub - drone-runners/drone-runner-aws: Experimental Drone runner that executes pipelines on single-use virtual machines and https://docs.drone.io/runner/aws/installation/
It has windows EC2 instance and support for docker on windows too. We are hoping that this will help a lot of our users.

There is a lot to support out there and we are trying are best, so thank you for your patience. We are looking at more support for other architectures too.
