USB Block: Control Access to Connected Devices

A free software program that selectively blocks certain USB devices while allowing access to others, useful for controlling access in public computers or kiosks.

What is USB Block?

USB Block is a lightweight application designed to help prevent unauthorized access to USB storage devices connected to Windows computers. It allows administrators to selectively restrict access to certain USB devices based on various criteria.

Some key features of USB Block include:

• Selectively blocking USB devices by device type, vendor ID, product ID, or serial number
• Allowlisting specific USB devices to ensure access
• Customizable access restriction rules
• Password protection of configuration settings
• Portable version available that doesn't require installation
• Free for personal and commercial use

USB Block runs quietly in the background and blocks access to restricted USB devices as soon as they are connected. It prevents processes and explorers from accessing the drive. A notification is displayed alerting that the USB device has been blocked.

The software is useful for controlling USB access in public computers, schools, libraries, hotels and other shared devices where USB devices pose a security risk. It allows granular control over which devices are accessible.
