The WPD Devices: Deny write access machine setting should be configured correctly. This policy setting denies write access to removable disks, which may include media players, cellular phones, auxiliary displays, and CE devices. If you enable this policy setting, write access will be denied to this removable storage class. If you disable or do not configure this policy setting, write access will be allowed to this removable storage class. Fix: (1) GPO: Computer Configuration\Administrative Templates\System\Removable Storage Access\WPD Devices: Deny write access (2) KEY: HKLM\Software\Policies\Microsoft\Windows\RemovableStorageDevices\{6AC27878-A6FA-4155-BA85-F98F491D4F33}\Deny_Write
