This setting determines whether data in the CD-ROM drive is accessible to other users.

Because the CD-ROM drive is a volume, by default, it is shared as an administrative share on the network. If the value of this entry is 1, the CD-ROM drive is allocated to the user as part of the interactive logon process and, therefore, only the current user can access it. This prevents administrators and remote users (and even the same user at a different workstation) from accessing the drive while the current user is logged on to the computer. The drive is shared again when the current user logs off the computer.

Value Meanings:

Note: This value entry satisfies, in part, the C2 security requirement that you must be able to secure removable media.

		(Default)	REG_SZ	(value not set)
