I had to modify the startup params of the Docker Engine service to point to the User group installed with the Github actions runner. I also had to make this modification using the registry editor as the GUI for the services would not accept a parameter change, more on this here: https://serverfault.com/questions/507561/in-a-windows-service-will-the-start-parameters-be-preserved-if-the-start-is-of

Example: "C:\Program Files\Docker\dockerd.exe" --run-service -G GITHUB_ActionsRunner_XXXXXX"
