Windows HostProcess containers can run containerized workloads on a Windows host. These containers operate as normal processes but have access to the host network namespace, storage, and devices when given the appropriate user privileges. HostProcess containers support the ability to run as one of the following Windows service accounts: LocalSystem, LocalService, NetworkService.
