Windows 2000 does not use this subkey. The subkey remains in the registry to support programs designed for Windows NT 4.0 and earlier.

In Windows NT 4.0 and earlier, this subkey contained information about all physical disk drives, logical partitions of disk drives, CD-ROM drives, and network drive mappings on the computer. Windows 2000 eliminates this subkey and stores similar information in the MountedDevices subkey.
