Using Group Policy to make Win7 stop unfamiliar U disk boot

The current network is very popular, but I have to admit that many times U disk is still an indispensable exchange tool. Like all external media, this feature of the USB flash drive makes it a natural virus carrier. It is often exchanged and it is easy to bring the virus Trojans from other computers back to our computer. Is there any way to make Windows smarter, automatically identify your U disk and reject other U disk?
1, prohibit other U disk insertion

The whole operation is divided into two stages, the first is Let Win7 know your U disk, and then set the rules to let the system automatically reject other U disk computer knowledge.
First step. Insert your U disk into your computer, then open [Device Manager], expand [Computer] → [Disk Drive], and then find your U disk.
2, find your own U disk

Second step. Double-click the U disk item to enter the property page, then open the [Details] panel and change the [Properties] to [Hardware ID]. Then copy the first value in the hardware ID.
3, record the U disk "hardware ID";

The third step. The same operation, the [Universal Serial Bus Controller] → [USB mass storage device] hardware The ID is copied, and the specific steps are the same as above.
4, record the USB mass storage device "Hardware ID"

Step 4. Click the Start menu, enter "ldped;gpedit.msc" in the search bar, start the Group Policy Editor.
5, start [group policy editor]

the fifth step. Find and expand [computer configuration] → [management template] → [system] → [equipment installation] → Equipment installation restrictions].
6, find [equipment installation restrictions]

Step 6. Open [Do not install devices not described by other policy settings] and [Allow installation of devices matching the following device IDs], and Fill in the hardware ID of the U disk and USB mass storage device just copied to the [Display] panel of [Allow installation of devices matching the following device IDs].
7, fill in the U disk hardware ID just recorded

Well, click OK, the configuration will take effect, just plug in a U disk and try it. How, the power of Group Policy is not very powerful!
8, other U disk inserted is blocked by Group Policy
