Disable "TFTP Client" feature

Overview

About this script

This script improves your privacy on Windows.

These changes use Windows system commands to update your settings.

This script disables the "TFTP Client" feature.

The TFTP Client supports file transfers using the Trivial File Transfer Protocol (TFTP). TFTP protocol is insecure because it lacks authentication and encryption capabilities 1 2 3. This makes data transferred via TFTP vulnerable to eavesdropping and tampering 2 3.

Although TFTP's simplicity can be advantageous in certain contexts, such as configuring network devices, its security risks generally outweigh these benefits. Disabling it helps mitigate the risk of unauthorized data access and simplifies system security management 1 2.

Caution

Disabling a networking component may cause connectivity issues if required for specific operations.
