Now the network has been very popular, but have to admit, many times the U disk is still an indispensable exchange tool. Like all external media, this feature of U disk also makes it a natural virus carrier, exchanging operations frequently, and it is easy to bring viruses from other computers back to our computers. Is there any way to make Windows smarter, automatically identify their own U disk and reject other u disk?

1, prohibit other U disk insert

The whole operation is divided into two stages, the first is to let Win7 know your u disk, followed by the rules to allow the system to automatically reject other U disk computer knowledge.

The first step. Insert your USB drive into your computer, then open Device Manager, expand computer → disk drives, and then find your own USB key.

3, record the "Hardware ID" of u disk

The third step. The same operation, the "Universal Serial Bus Controller" → "USB mass storage Device" in the Hardware ID copy down, the detailed steps above.

4, record the USB mass storage device "Hardware ID"

Fourth step. Click the Start menu, enter "Gpedit.msc" in the search field, and start the Group Policy Editor.

5, start the Group Policy Editor

Fifth step. Locate and expand the computer configuration → administrative Templates → system → device installation → device installation restrictions in turn.

6, find "Device installation Restrictions"

Sixth step. Open "Prohibit installation of devices not described by other policy settings" and "Allow installation of devices that match the following device IDs". And the hardware ID of the U disk and USB mass storage device that you just copied is filled in the display panel of "Allow devices that match the following device IDs to be installed."

OK, click OK after the configuration will begin to take effect, just insert a U disk try it. How, the power of Group Policy is not very powerful!
