+### Specify isolation technology for container (--isolation)
+
+This option is useful in situations where you are running Docker containers on
+Windows. The `--isolation=<value>` option sets a container's isolation
+technology. On Linux, the only supported is the `default` option which uses
+Linux namespaces. On Microsoft Windows, you can specify these values:
+
+
+| Value     | Description                                                                                                                                                   |
+|-----------|---------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| `default` | Use the value specified by the Docker daemon's `--exec-opt` . If the `daemon` does not specify an isolation technology, Microsoft Windows uses `process` as its default value.  |
+| `process` | Namespace isolation only.                                                                                                                                     |
+| `hyperv`   | Hyper-V hypervisor partition-based isolation.                                                                                                                  |
+
+Specifying the `--isolation` flag without a value is the same as setting `--isolation="default"`.
