How can I make the Win7 system use the specified USB flash drive to protect the system?

  

The USB flash drive is a convenient file storage and mobile tool, but it may also cause your important data to be stolen by a USB flash drive. Can the system only use the U disk we specify, other U disk can not access it? Of course, Xiaobian teach you how to operate under Windows 7.

We can let Windows 7 do this through Group Policy. By setting it is possible to disable all USB storage devices, and also allow the system to use only the USB flash drive you specify.
