You want to load a registry hive or key with a command line
This is by design
Under normal circumstances the import of the regkey will show you a popup messages. To deactivate this you can start regedit with /s (=silent). e.g.
regedit /s c:\temp\myregkey.reg
A regfile from NT 4 can be imported with regedit version 5 as long as the keypath is still the same!
