Computer Configuration\Administrative Templates\System\File System Description
Dev drive or developer volume is a volume optimized for performance of developer scenarios. A developer volume allows an administrator to choose file system filters that are attached on the volume. Disabling this setting will disallow creation of new developer volumes, existing developer volumes will mount as regular volumes. If this setting is not configured the default policy is to enable developer volumes while allowing antivirus filter to attach on a deveveloper volume. Further, if not configured, a local administrator can choose to not have antivirus filter attached to a developer volume. A reboot is required for this setting to take effect.
