Disable thumb drive on PC

Recently I was asked to configure a laptop to be very closed, i.e, disable most of communications with internet, external spaces, etc, and from the work i found the trick to disable the use of USB mass storage device without disabling all the USB ports, see below:

When a external USB storage device is plugged into the computer, a new tree node "USB mass storage device" in "Device Manager>Universal Serial Bus Controller" will show, so go straight to disable it will disable use of USB storage devices including thumbdrives, if you have tried it, you will notice after it has been disabled, plugging in the thumbdrive will not be detected any more : )

Another way is to edit the registry value, under 'HKEY Local Machine > System > CurrentControlSet > Services > USBStor', change the start value to 4, which results in similar consequences, that the plugged in device will not be detected.
