 ## Privileged mode for containers
 
-In Linux, any container in a Pod can enable privileged mode using the `privileged` (Linux) flag on the [security context](/docs/tasks/configure-pod-container/security-context/) of the container spec. This is useful for containers that want to use operating system administrative capabilities such as manipulating the network stack or accessing hardware devices.
-
-If your cluster has the `WindowsHostProcessContainers` feature enabled, you can create a [Windows HostProcess pod](/docs/tasks/configure-pod-container/create-hostprocess-pod) by setting the `windowsOptions.hostProcess` flag on the security context of the pod spec. All containers in these pods must run as Windows HostProcess containers. HostProcess pods run directly on the host and can also be used to perform administrative tasks as is done with Linux privileged containers.
