Removable USB devices have become an essential part of our electronic life, since these portable devices have the ability to carry GBs of information in them and therefore prove handy at times. However, the same can also be used to upload malicious code to your computer (intentionally or unintentionally) or extract confidential information. So, the best way to avoid such hassle is prevent users from connecting any USB devices to your system. There appears to be no direct and easy way of doing it in Windows. That said, you can always make use third party applications under such circumstances.
Kashu USB Flash Security is a free utility for password protecting USB keys and other sensitive data stored in it.
