The list of available restrictions and a range of other security options are available, such as blocking access to the Registry Editor, disabling the auto-play facility and preventing users from creating CDs and DVDs. At the bottom of the screen, a list of hard disks and removable drives is displayed. By ticking the box next to any of these drives, they can be hidden from users, thereby making them harder to access. This is a handy way to block access to various removable media.
