Controlling block storage devices on USB buses

What does controlling block storage devices on USB buses do?

This feature provides the ability to set a registry key that will prevent
write operations to USB block storage devices, such as memory sticks. When
this registry key is enabled, the devices function only as read-only
devices. You can implement this setting as part of a security strategy to
prevent users from transporting data using these devices.

Who does this feature apply to?

. Users who do not want data to be written from their computer to a USB
storage device.

. IT professionals who want to implement organization controls over the use
of USB block storage devices
