This policy setting deletes all data stored on Windows SideShow-compatible devices (running Microsoft firmware) when a user logs off from the computer. This is a security precaution but it significantly limits the usefulness of the devices.
If you enable this policy setting, all data stored on devices running Microsoft firmware will be deleted when a user logs off from the computer. Data will be re-sent to the device when the user logs on again.
If you disable or do not configure this policy setting, data will not be deleted from these devices when users log off from the computer. Users can enable this setting in the Windows SideShow Control Panel.
Note Devices not running Microsoft firmware will not be affected by this policy setting.
