Lock and Unlock Your USB Ports

If you are comfortable working with Regedit, the key you want to go to is HKEY_LOCAL_MACHINE\SYSTEM\CurrentContro>Set\Services\USBSTOR. The value inside the key is start. If you want to disable USB storage, change start's data to 4 and want to enable it change the data 3.

But let me give you an easier way to change it. Copy and paste the below code into notepad.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR]”Start”=dword:00000004 

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR\Enum]”Count”=dword:00000000”NextInstance”=dword:00000000

Result should be look like this

Now save the file in suitable location and name it disableusb.reg. Make sure it's saved as a ".REG" file not ".TXT" file. You can tell by its icon.

Now repeats the process with these two changes.

Before you the file, go to the line that reads "start"=dword:00000004 and now change the 4 to a 3.
Now save the file as enableusb.reg.

Launching disableusb.org and confirm the change. You have to disable USB-connected storage. Note, It wouldn't affect storage already connected, but it will block any external drive that is connected after you make the change. Launching enableusb.reg. of course, re-enable it.

How can you keep other people from launching enableusb.reg? You need to have an  administrator-level account to change the registry. Supposing that only you have an administrator account, and that you have not shared the password, only you will be able to make these variations.
