The CD and DVD: Deny read access machine setting should be configured correctly. This policy setting denies read access to the CD and DVD removable storage class. If you enable this policy setting, read access will be denied to this removable storage class. If you disable or do not configure this policy setting, read access will be allowed to this removable storage class. Fix: (1) GPO: Computer Configuration\Administrative Templates\System\Removable Storage Access\CD and DVD: Deny read access (2) KEY: HKLM\Software\Policies\Microsoft\Windows\RemovableStorageDevices\{53f56308-b6bf-11d0-94f2-00a0c91efb8b}\Deny_Read
