Part 1. What Is USB Port Blocker Software

These tools are focused on giving you control over access to USB ports in your machine. USB port security lock software can prevent all external USB drives from connecting to your PC. Depending on the tool, you might also have the option to restrict only writing to external drives. That way, you can open USBs but cannot copy or create new files and folders within them.

A USB blocker is a tool that focuses on protecting your data and computer overall. It features a graphical interface that is easy to use. You can pick between simple tools focused on a couple of basic functions or advanced apps with a bunch of advanced features.

Part 2. Who Should Get An USB Port Blocker Software

Are you wondering whether you need USB block software? Here are some situations where you could benefit from these apps:

  • Protecting the data on your PC – if you are working with sensitive files and want to keep them protected, using these tools can prevent unauthorized copying to third-party flash drives.
  • Prevent viruses from entering your machine – flash drives could be loaded with viruses, which is why blocking them is the best way to prevent malicious files from entering your machine.
  • Have total control over connected USB drives – apart from preventing USB port access, these apps can also whitelist specific devices. That puts you under total control of which flash drives can safely be connected to your PC.

Part 3. How We Tested and Picked the Best USB Port Blocker Software for Windows 11/10/8/7 in 2024

Are you looking to pick the best USB port security lock software but are unsure where to start? Before you read our reviews below, check out the factors we considered when selecting the products. We tried to analyze all major features, and those include the following.

Can It Block Reading and Writing to USB Drives?

The best USB-blocking software should be capable of preventing both the writing and reading of USB drives. If you want to have access to USBs, choosing to block writing to those drives is recommended. That way, you can access the files on the drive but cannot add new content to it. It is a convenient way of protecting your machine.

Unlike that, preventing the machine from reading USB drives will block them completely. Inserting a flash drive into the USB port won’t give any results since the PC will be blocked from reading it.

What Other Functions Are Available?

The most useful function that USB blockers can offer is password protection. If you want to protect your data, you can’t risk someone overriding the settings you placed with the tool. That is why requiring a password when changing the settings or uninstalling the tool will boost the protection levels.

These tools might also be capable of blocking programs, websites, and other external devices, such as printers or modems. However, not all apps come with these functions. If you feel like you need them, choose a tool that implements these features.

User Interface

A user-friendly interface is mandatory when using USB block software for Windows 10. It will ensure that even beginners can set the desired adjustments easily. Most developers put in great effort to ensure that their interface is attractive and clean.


Free USB port security lock tools are available on the market, and they usually come with basic functions. But if you want ultimate control over USBs and other external drives, premium apps might deliver the additional features you need. Ultimately, pick the tool that fits your budget while meeting all the expectations you have from this type of app.
