To get the list of Windows agents that do not have EDR activated, navigate to the Cloud Agent app from the module picker and click Agent Management > Agents. On the Agents window tab, perform a search using the following query:
not activatedForModules:"EDR" and operatingSystem:"Windows"
Once the list is populated, you can activate the Windows agent for EDR. For more information, see step 6 on Install Cloud Agents for EDR.
