Six strategies of how to disable U disk

1. Deactivate equipment

Right-click on my Computer--> management, and then select Device Manager--> Universal Serial Bus controller--> has two USB root hub disable these two items inside: Conventional--> device method--> Deactivate

　　2. Disable in BIOS type

Enter the BIOS settings, select the "Integrated peripherals" option, expand the "Usb1.1controller" and "usb2.0contr01ler" option to set the properties to "Disableed", you can disable the USB interface. Finally, do not forget to set a password on the BIOS so that others cannot solve the "lock" device by modifying the registry.

Note: This method is completely prohibited USB interface, which means that all kinds of USB interface devices can not be used, of course, also includes a U disk and mobile disk.

　　3. Prohibit the installation of USB driver

In Windows Explorer, go to the system disk: Windowsinf directory, locate the file named "USBSTOR.PNF", right-click the file, select Properties from the pop-up menu, and switch to the Security tab, in the group or user name box, select the user group you want to suppress, and then in the Permissions box of the user group, check the Deny checkbox after Full Control, and then click OK.

　　4. Open start "Run" Enter regedit carriage return

Open Registry Editor, expand the following branch [Hkey_local_machinesystemcurrentcntrolsetservicesusbstor], and locate the DWORD named "Start" in the right-hand pane, double-click, In the pop-up Edit dialog box, change its numeric data to 16-bit binary value "4". Click OK and close the Registry Editor to restart the computer for the settings to take effect. After reboot, when someone connects a USB storage device to the computer, the USB device cannot be used, although the LEDs on the USB device are blinking normally, but the letter is not found in the resource manager.

　5. Download the latest version of Super Rabbit, choose--> Super Rabbit Magic set--> files and media-->u disk--> prohibit the use of U disk savings function

There are a lot of software to provide a U disk prohibit function, I will not say it all

At the same time I provide a U disk prohibit automatic playback method

　6. Hide Letter and no view (for Windows system)

Open Registry Editor, expand the following branch [Hkey_current_usersoftwaremicrosoftwindowscurrentversionploiciesexplorer], and create a new binary value, "NoDrives", The default value is 00000000, which means that no drives are hidden. The key value consists of four bytes, each bit of each byte corresponds to a disk from a: to Z: When the corresponding bit is 1 o'clock, the corresponding drive in My computer is hidden. The first byte represents 8 disks from A to H, that is, 01 is a,02 b,04 for C ... By analogy, the second byte represents I to P, the third byte represents Q to X, and the fourth byte represents Y and Z. For example, to close the C disk, the key value to 04000000, to turn off D, to 08000000, to close the C and D disk, then to 0c000000 (c is hexadecimal, turn into decimal is 12). After understanding the principle, take my computer as an example to illustrate how to: My Computer has a floppy drive, one hard disk (5 partitions), one optical drive, the letter distribution is as follows: A: (3.5 floppy disk), C:, D:, E:, F:, G:, H: (CD), so my "NoDrives" as " 02ffffff ", hide B, I to Z disk. Restart the computer, and then insert a U disk, I can not see it in my computer, but in the address bar input I: (My computer after a letter is h) or access to the mobile disk. Here everyone can see "NoDrives" is just a camouflage, so we have to do one more step, is to create a new binary "noviewondrive", the value changed to "02ffffff", that is, its value and "NoDrives" the same. As a result, can not see the U-disk and can not access the U disk.
