Let the Win7 system only use the designated U disk to protect the system security

U disk is convenient and easy to use the file storage and mobile tools, but also may lead to their own important information data are stolen with U disk. Can you allow the system to use only our own designated U disk, other U disk can not access it? Of course, I'll teach you how to operate under Windows 7.

We can use Group Policy to get Windows7 to do this task. By setting up, you can disable all USB storage devices and also allow the system to use only the USB drive you specify.

Operation Steps

1. First of all we have to do is to put their own U disk into the computer first, allow the system to use the U disk normally, then go to "Control Panel", double-click "Device Manager", "USB Mass Storage Device" property → details → Property's hardware ID, and save the hardware ID of the Universal Serial Bus controller.
