How To Enable Disable Write Protection Of USB Devices ( Using Windows)

Microsoft has added options to the Windows operating system (more precisely to Windows XP and newer operating systems) to write protect all USB devices that are connected to it. This indicates that it may not always be possible to protect the computer this way, for instance if data needs to be written to USB devices regularly.

Write Protection adds another layer of defense to the computer. The system is not fool proof on its own, as it is still possible to copy data, for instance by uploading it to the Internet or a network connection.
