Windows USB Blocker

Windows USB Blocker is a small software application whose sole purpose is to help you lock your USB flash drives with just one click.

You should take into consideration that only the flash drives or portable storage devices like external hard drives are blocked by the program, so the wireless or Bluetooth adapter of your mouse, keyboard, headphones, and speakers function normally.

There’s not much to brag about the user interface, as it embeds only a few configuration settings that you can play with. The tool implements an intuitive behavior, so even less experienced users can learn to master the entire process in no time.

Windows USB Blocker gives you the possibility enable or disable your USB flash drives with just one click. You can either click on the built-in button or icon for triggering the process.

When you enable the blocking mode, the AutoRun function is disabled, so your computer is not able to automatically detect that your USB is plugged in. You cannot view the USB flash drive’s corresponding letter in your Windows Explorer.

Tests revealed that Windows USB Blocker carries out a task quickly and without errors. As it would be expected from such a small utility, it manages to remain light on the system resources, so it doesn’t burden the overall performance of the computer, nor interfere with other programs’ functionality.

All things considered, Windows USB Blocker makes the entire process seem nothing but a piece of cake, and is suitable for all types of users, regardless of their experience level. If you want to skip the installation steps, you can check out the portable version of the program, which can be found here.
