This article explains how to silently and cleanly uninstall the CyberFOX DNS Roaming Client from Windows devices. Uninstalling the agent removes DNS policy enforcement and removes the device from active monitoring in the CyberFOX DNS Filtering Portal.

What the Uninstall Process Does

Removing the DNS Roaming Client:

• Stops DNS interception and routing through CyberFOX Filtering.
• Removes the agent service (CyberFOX DNS Client).
• Deregisters the device from the DNS Filtering dashboard.
• Restores the system's default DNS resolver behavior.

Use the uninstall method below when offboarding devices, repurposing machines, or migrating to a new environment.

Platform‑Specific Uninstall Steps

Windows (Standard Uninstall Command)

The client can be removed silently using the following command:

"%ProgramFiles%\CyberFOX DNS Client\unins000.exe" /SP /SUPPRESSMSGBOXES /VERYSILENT /NORESTART

Execution notes:

• Must be run with administrative privileges.
• The device must be restarted to fully release DNS hooks (RMM can trigger later).
• Recommended for RMM automation, PowerShell, batch scripts, or GPO.

Windows (Manual Uninstall)

1. Open Control Panel → Programs and Features.
2. Locate CyberFOX DNS Client.
3. Click Uninstall.
4. Restart the device.

Advanced Use Cases

RMM / MSP Automation

• Use global scripts to remove stale clients.
• Pair uninstall commands with a hostname check to confirm device identity.
• Schedule bulk customer migrations using automated tasks.

Hybrid Environments

• Use uninstall routines during OS imaging or workstation refresh cycles.
• Validate removal by checking that outbound DNS no longer resolves via the CyberFOX network.

Troubleshooting

Agent Still Appears in Portal

• Portal may take up to 5 minutes to refresh device status.
• Ensure the device is online for its final heartbeat before uninstall.
• Manually remove the stale entry under Roaming Clients if needed.

DNS Still Appears Redirected

• Confirm reboot was performed.
• Verify no GPO or third‑party agent is forcing DNS.
• Check network adapter DNS settings for static overrides.

Uninstall Command Fails

• Confirm Program Files path uses the correct architecture.
• Run PowerShell as administrator:

  Start-Process -FilePath "C:\Program Files\CyberFOX DNS Client\unins000.exe" -ArgumentList "/VERYSILENT" -Verb RunAs
  

• Verify service is not locked by security tools.

Security & Sync Behavior

• Once uninstalled, the device no longer sends DNS telemetry.
• Policy enforcement stops immediately after the agent service is removed.
• No personal data is retained on the endpoint after uninstall.
• Deregistration does not affect other CyberFOX products (Password Boss, AutoElevate, etc.).
