Since its introduction, USB has provided an amazing advancement in what we can do with our computers. It allows us to connect devices as varied as keyboards, mice, printers, external storage, and more. Unfortunately, it also provides a way for someone to quickly copy data off your computer. You may find it helpful at times to restrict the ability of USB storage devices from being used with your computer. By editing the Registry Editor, you can turn this functionality on or off as you need it, while still allowing use of your USB keyboard, mouse, and USB printers.

To disable USB storage devices, follow these simple steps:

  1. Press Windows+R. Windows opens the Run window.
  2. Type "regedit" (without quotes) and press Enter. Windows opens the Registry Editor.
  3. In the left-side panel, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\usbstor. Once you do you will see several options in the right-side panel.
  4. In the right-side panel select the item named "Start" and double-click. This brings up the Edit DWORD (32-bit) Value dialog box. (See Figure 1.)

    5. Figure 1. Edit DWORD (32-bit) Value dialog box.

  5. In the Value data field change the "3" to a "4" (without quotes).
  6. Click on OK to close the dialog box.
  7. Close the Registry Editor app.
  8. Restart your computer for the setting to take effect.

To re-enable the USB ports, repeat the steps above, and at step 5 change the "4" back to a "3" and restart your computer.

By disabling USB storage devices access to your computer, you can help ensure that your information is safer on your computer, and not on your friend's USB device.

You just create a couple of ".reg" files, one enable USB storage and the other doable it. Either can be imported into the registry by right clicking and choosing "Merge".

The easiest way to create the .reg file is to open regedit and export the relevent key. Make a copy for the disable file and edit the key value (4).
