Top 5 Best Free USB Port Blocker For Windows


If you have heard of USB port blocker, you may be wondering if you need to get one for your system, or why you may need one in the first place.

What is a USB Port Blocker

USB port locking/blocking software is able to block your computer from reading any USB Flash drive. This may be very important knowing that USB Flash drives are one of the most significant potential threats to your system.

If you are accustomed to having people around your work environment of friends use your computer, then you may consider one of these.

Some port blockers will come with support for adding a password to change the USB port block settings, and others may provide support to use USB port as read-only.

In this article, I will give you a list of some of my favorite free USB port blockers.

Free USB port blockers

There are not so many that will enter my list, especially since most of the great value will come at a premium price. But still, there are a few that get the work neatly done and are free.

1. BuduLock

This is a great one and is definitely worth the mention in my list. With its 2 tabs; one for folder lock and the other for USB lock, it is really easy to use.

This simple USB port lock software for Windows can be used to lock folders. Even though it will not totally serve the function to lock USB port, it also blocks USB flash drives and memory drives.

When using Budulock, devices such as the mouse, keyboard, and webcam will work properly even when the lock is active.

Once the USB flash lock is enabled, your computer will not access any USB memory drives. You can increase security by using the change password feature.

2. USBDeview

USBDeview makes the list for the support for remote port blocking. It allows one to block a port on another system.

USBDeview is a USB port manager which lets you enable and disable USB port lock. It allows one view the list of USB ports and a list of the devices connected to them.

Another feature that makes this freeware special is that it allows one choose and block specific ports.

3. Nomesoft USB Guard

If you need a USB port blocker with a nice, simple and easy to use interface, then it has to be Nomesoft SB Gaurd. It basically gives two main options. You can either entirely block USB detection, or make the USB device read-only. The downside to this freeware is that it may not maintain support for windows 10.

4. Ratool

This tool does a pretty good job at right protecting. Ratool has a sleek interface that allows three basic functions:

  1. Allow Read & Write – this is the default
  2. Allow Read-only
  3. Block USB Storage Devices

Ratool will by default “lock” its changes to write access. This makes them much more difficult to remove and harder to bypass without proper access.

You must note that this is my preferred list and it is represented in no particular option. Of course, there are premium software that will get the job done much better than this freware, but if you looking for basic and simple security, feel free to dig in.
