Hives (registry data) saved from a Windows NT 3.5 machine with the
RegSaveKey() API (application programming interface) cannot be restored on
a Windows NT 3.1 machine with RegLoadKey(), because the hive format for
Windows NT 3.5 is different than the Windows NT 3.1 format (it has been
made more efficient). However, Windows NT 3.5 supports both the new and old
(Windows NT 3.1) hive formats, so hives created on a Windows NT 3.1 machine
can be used on a Windows NT 3.5 machine.
 
To create a hive on Windows NT 3.5 that can be used on Windows NT 3.1, use
the Win32 registry APIs to read the registry key by key, and save the
values in your own text format. Use the APIs to restore the registry
information on either version of Windows NT.
