Disable USB Ports in Windows

You must be familiar with the term USB ports. This can be found on any desktop or on laptop computers too. This article especially tells you the ways to disable USB ports on any Windows PC.

Before we start, let us discuss the System USB ports.

However, you must be aware of the USB ports on the computer, but still let me brief you a little about it. If somebody does not know about USB ports, this can help that person.

In computer language, a USB port stands for Universal Serial Bus port that helps USB devices to connect each other with the help of serial cable for communication between both devices.

By doing this, you can transfer any data digitally after a stable connection of both devices (computer and USB device). For example, you can use USB ports to connect a flash drive, USB keyboard or USB mouse.

Benefits of Disabling USB Ports

I am not denying that USB ports are useful. By using system USB ports, you can connect to any flash drive or a pen drive for data transfer, to connect to any USB printer, USB speakers, USB scanners, and connect digital cameras to transfer photos and videos.

Nevertheless, what if you do not use most of them and access your system for browsing or knowledge purposes only?

Several times not intestinally, if some of your friends or family members connect their USB flash drive or camera just to transfer data, but who knows that the devices they connected to your system are not infected with viruses.

Denying anyone not to connect a USB device to your system feels very awkward. Instead, you can disable USB ports easily.
