The strategy of prohibiting U disk from booting on computer

On the computer prohibit the U disk to start the strategy:

　　Method One:

1, the first is the BIOS set, we generally boot press del or F2 into the BIOS, select integrated peripherals.

2, into the integrated peripherals, we will be USB 1.1 controller and USB 2.0 controller press ENTER to open, change it to disabled.

This reboot is OK, however, some external USB devices can not be used, and now there are so many USB external devices, for ease of use is not recommended in this way.

　　Method Two:

1, right click on "My Computer", select "Properties".

2, select "Hardware" bar, click "Device Management", pop-up "Device Management" window.

3, find "Universal Serial Bus Controller", as shown in the figure, to find the USB bulk storage items, right click to deactivate it. However, to choose the right USB interface, sometimes the mouse or keyboard and other USB ports are deactivated. Stop using the wrong and then change back on the line. But this method does not have much effect on people who know more about computers.

　　Method III: Modify the registry, but also a more common method.

1, click to open the Start menu, select "Run".

2, in the "Run" window, enter "regedit". Point OK.

3, we first find hkey_local-machine.

4, and then find SYSTEM currentcntrolset.

5, and then find the following services.

6, and then continue to find the following Usbstor folder.

7, in the folder to find "Start" Double-click to open it, the value must be 4. and click OK to save, then reboot on it.

After using this method, if you have 360 security guards or Golden Hill guards on your computer, sometimes you can change the system repair or registry modifications. It is recommended that you do not install these on your computer.

　　Method Four:

Finally, I also think that a class of methods is most useful, I heard that some units directly to the chassis panel of the USB port directly to die, this is more than any modification of the system installed software is effective, you can not weld dead, the chassis front panel USB port will be dialed off, buy when the USB interface less, the chassis only to leave the necessary USB interface on the line.
