+### Specify isolation mode (Windows)
+
+By default, tasks scheduled on Windows nodes are run using the default isolation mode 
+configured for this particular node. To force a specific isolation mode, you can use 
+the `--isolation` flag: 
+
+```bash
+$ docker service create --name myservice --isolation=process microsoft/nanoserver
+```
+
+Supported isolation modes on Windows are:
+- `default`: use default settings specified on the node running the task
+- `process`: use process isolation (Windows server only)
+- `hyperv`: use Hyper-V isolation
+
