+= Enabling override Operators
+
+To make sure {prod} can run on a typical laptop, some resource-heavy services get disabled by default.
+These services can be enabled by manually removing the desired Operator from the Operator override list.
+
+.Prerequisites
+
+* A running {prod} virtual machine and a working [command]`oc` command.
+For more information, see link:{crc-gsg-url}#accessing-the-openshift-cluster-with-oc_gsg[Accessing the OpenShift cluster with `oc`].
+* You must log in through [command]`oc` as the `kubeadmin` user.
+
+.Procedure
+
+. List unmanaged Operators and note the numeric index for the desired Operator:
+
+** On Linux or {mac}:
++
+[subs="+quotes"]
+----
+$ oc get clusterversion version -ojsonpath='{range .spec.overrides[*]}{.name}{"\n"}{end}' | nl -v 0
+----
+
+** On {msw} using PowerShell:
++
+[subs="+quotes"]
+----
+PS> oc get clusterversion version -ojsonpath='{range .spec.overrides[*]}{.name}{"\n"}{end}' | % {$nl++;"`t$($nl-1) `t $_"};$nl=0
+----
+
+. Start the desired Operator using the identified numeric index:
++
+[subs="+quotes"]
+----
+$ oc patch clusterversion/version --type='json' -p '[{"op":"remove", "path":"/spec/overrides/_<unmanaged-operator-index>_"}]'
+clusterversion.config.openshift.io/version patched
+----
