How can I block a USB storage device from accessing windows?

Joralyn Pingal,

          There are hundreds of ways to block USB devices from accessing your PC. But most of the solutions are complicated. But there is a smart solution for you. For this you need to have a program called myusbonly.

          Myusbonly  program is very simple to install and is unique because it will block other USB devices from accessing your PC but it will not block your USB. That's the thing we need. If you can install the program following the simple instructions, then you can run it.

          You should now see a small window, where it shows you that Myusbonly is running in your desktop task bar. Click  on it and click on general set up. Then go according to what you want. This might help you.

Thank you very much.

The ADM template simply sets the registry value

    HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesUsbStorStart to 4 (Disable).

        But his technique has a serious drawback. It only works if the USB storage driver is already installed. If it has not yet been installed, Windows' plug & play subsystem automatically resets the Start value to 3 (Manual) when it installs USBSTOR after a USB storage device is plugged in for the first time. In that case, USBSTOR remains enabled until the GPO is re-applied, usually at the next reboot.

          If the storage device is plugged in during that reboot, it will still be available because the USBSTOR driver is started before any GPOs are processed.

Hi,

There are several ways to do it. Let me explain some methods. Are you using a domain environment in your business? if you are using domain environment simply you can block your USB ports by using a group policy but I won't discuss about it in here. You can simply edit your registry setting in the computer to block USB ports. you need to have admin privileges ( local administrator rights )

This is the way to block USB ports:

1. Type regedit in the RUN
2. Hit enter button
3. Regedit will appear, now you need to find out the specific registry entry to disable USB devices
4. Press Ctrl+F to find dialog box to find the registry entry that we need, after  type USBSTOR and wait until it finds the required registry entry, finally it will point you to the relevant registry entry that we want.
5. Now right click on default value and select modify from the pop up menu;

Then type 3 inside the value date area ;

You are done now.

No more USBs, but keep that in your mind that everyone including yourself is not allowed to plug USB pen drives to the computer after editing the above registry entry.

Cheers!
