Remove the registration record for an Agent Client Collector (ACC) agent from your ServiceNow instance after uninstalling the agent from a device.

## Before you begin

The agent must be uninstalled from the device. For details, see [Uninstall the Agent Client Collector agent from a device](https://www.servicenow.com/docs/37OHxGZWlXFHZSL6L3XS6w "Remove the Agent Client Collector (ACC) agent from a device to clean up the device after testing or decommissioning, or to reinstall the agent with different configuration settings.").

Role required: agent_client_collector_admin

## About this task

Deregistering an agent deletes its registration record. Deregister an agent only after you uninstall it from the device. If the agent is still installed and running, it can re-register with your instance.

## Procedure

1. Navigate to AllAgent Client CollectorAgents.
2. Note the agent IDs that you want to deregister.
3. Navigate to AllAgent Client CollectorAgent Registration.
4. Select the agents that you want to deregister.
5. Delete the selected records.  
   The agents no longer appear as registered on your instance.
