Windows Server 2025 must not have the TFTP Client installed.

Unnecessary services increase the attack surface of a system. Some of these services may not support required levels of authentication or encryption or may provide unauthorized access to the system.

Open PowerShell.

Enter "Get-WindowsFeature | Where Name -eq TFTP-Client".

If "Installed State" is "Installed", this is a finding.

An Installed State of "Available" or "Removed" is not a finding.

Uninstall the "TFTP Client" feature.

Start Server Manager.

Select the server with the feature.

Scroll down to "ROLES AND FEATURES" in the right pane.

Select "Remove Roles and Features" from the drop-down "TASKS" list.

Select the appropriate server on the "Server Selection" page and click "Next".

Deselect "TFTP Client" on the "Features" page.

Click "Next" and "Remove" as prompted.
