HOW TO DISABLE USB PORT

Disabling USB ports can be a smart idea to add security to the computer. This can be really handy if the computer is on a public place where the chances of virus and other malware infection is really high. You can easily disable access to USB ports with the following registry hack:

1.                  Open the Registry Editor (Start -> Run -> Type regedit and hit Enter)

2.                        In the registry, navigate to the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor

3.                  In the right-side pane, double-click on “Start”.

4.                  In the “Value data” field enter 4 and click on “OK”.

5.                  Close the Registry Editor and reboot.
