Hello,
If you are searching for any article on how to disable USB drive then here is the solution for it. Below mentioned method explains how to disable ONLY USB storage devices (flash/Jump/external HD’s) completely without disabling keyboards, mice, etc.
The first thing you will do is that you will disable it from the BIOS setting but it may not be possible to secure the BIOS setting from other users to set by setting the password for it cause if you are going to do that on too many computer then you will have to remember the BIOS password for all the computer. If it is for few computer then your best option is to disable the USB ports in BIOS settings. Then, set a BIOS password. Finish up with case locks or other security hardware so that users cannot open the case, and then reset the CMOS memory.
What you will do if that may not be possible for you to remember the BIOS password for all of them and you do not want it to be disable from the BIOS.
If you want to do some tweaks in windows and if you are a real technician then you will read this sol
First thing to do is this solution.
I. Go to start >> run >> regedit and navigate to HKLM\system\currentcontrolset\services\USBstor.
II. Change the value of the REG_DWORD “Start” from Value Data 3 to 4. If the dword “Start” doesnt exist, create it. This will prevent a previously installed USB device from loading when the device is plugged into the machine. ((As most of you know this a Microsoft suggestion, which does work perfectly at disabling previously installed devices, however, this alone will not disable USB storage completely. If a user plugs a new USB storage device into the machine the device will install and the dword value will be reset to 3. Now if you incorporate adding this into a script it alone will disable USB drives, but only after a user plugs a device in, removes it without uninstalling it, logs off then logs back on, thereby running the script. This means that there is a window of opportunity for users to have access to new devices, this may be acceptable for some, but not for others.))
II. The next thing to do is to change the permisions on the USBSTOR key. You need to DENY full control on the “system” group.
What this does is denies everyone the ability to access the USBStor key, effectively killing the ability for any user (including admins) to install USB storage devices. Now the reason you deny the “system” group is because windows will use this account if no one is logged onto the machine yet. What I mean by this is if say you want to deny a group of users called “staff”, you would need to deny them using GP or a logon script. This will work great, but, if a “staff” group user plugs a USB drive in before logging in to Windows the device will be installed using in the backgroud using the “system” group, then when the user logs in the “staff” group policy is applied dening the user access to the USBstor key, but by this point it makes no difference because the devices is already installed and accessible and once a device is installed the usbstor key is no longer used.))
III. So now that these two steps are are done, *NO ONE* will be able to install USB drives.
If a user tries to use a previously installed drive the device will be blocked and nothing will happen, no prompts, nothing. This is accomplished through step 1, the dword value.
What happens if a user plugs in a “New” device that was not previously installed, the hardware wizard will run, asking for the location of drivers. Regardless of whether a user selects the “automatically” search and install or if they attempt to manually install 3rd party drivers, the HW wizard will prompt the user that “access is denied” once the drivers are selected. This is the result of step 2, denying “system”.
Now that we know how to disable USB storage devices we need to find an efficient way to do this without driving through the registry on each and every machine.
` killing USB drives quickly and easily.
Create 2 batch files, 1 batch to disable and another for administrators that will re-enable USB drives if the need arises.
1: First thing is to get a copy of the tool “subinacl.exe”. This tool is included with MS Server 2003 RK.
(What subinacl allows you to due is set specific permissions on the exact group or user, etc.. that you need to, this includes permissions on registry Keys which is what we will be doing.)
2: Once you have a copy of “subinacl.exe” set up a folder for your batch files. In my particular case I wanted these batch files available on the network so I created a shared folder named “DisableUSB” on a server. Next I created a subfolder within “DisableUSB” called “subinacl”. Put a copy of “subinacl.exe” in this folder.
3. Next thing to do is create 2 “reg” files in the subfolder “subinacl”. I named the 2 files “dword3.reg” and “dword4.reg”. These files are going to be used to change the value of the dword “start” in the registry key Usbstor.
I assume most probably know how do create reg files, this is what should be in the files:
For “dword3.reg”
******
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\USBSTOR]
“Start”=dword:00000003
*change the 3 to a 4 for “dword4.reg”*
4. Now put these 2 files in the “subinacl” folder if they weren’t created there.
All the pieces should now be in place. For this example we have a shared folder (on no particular server) called “disableUSB”. Within this folder is a subfolder “subinacl” that has subinacl.exe, dword3.reg, and dword4.reg within it.
5 . Now to create the 2 batch files. I created these 2 files under the main share folder (disableUSB). One is called “disableUSBdrives.bat” which, you guessed it, disables drives, and the other for re-enabling drives, “enableUSBdrives.bat”.
This is how disableUSBdrives.bat is set up:
@echo off
cls
regedit /s \\servername\disableUSB\Subinacl\dword4.reg
\\servername\DisableUSB\Subinacl\subinacl.exe /keyreg \system\currentcontrolset\services\usbstor /deny=system
pause
cls
echo.
echo **USB drives disabled**
echo.
Pause
*the path will differ of course. \\servername is just an example.
for “enableUSBdrives.bat” simply change change “dword4.reg” to “dword3.reg” AND “deny=system” to “grant=system”
Notice that the only real meat to these batch’s is running regedit and running subinacl. Everything else (cls,pause,echo) is optional, for my particular situation it was needed.
6. Go the machines that you want to disable USB drives on and run the disableUSBdrives batch from the network share.
And that’s it.
USB drives gone.
Now of course running a batch from each machine is still time consuming, but In my particular situation it had to be done this way, and is obviously much faster than driving through the registry.
The most efficient way to incorporate this would be with logon scripting. Unlike with just using the dword start=4 trick, after this script is run, there is no way for joe blow user to use any of his nifty little Jumpdrives or his hot new hard drives.
Also note that folder names and locations can be set up in any way and anywhere as long as the batch files point to the right place.
