Frank found that to export a registry key, add the specific location to the command such as:
REGEDIT /E c:\out.reg HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Id
To delete a registry key place a hyphen as the first character to the right of the bracket:
REGEDIT /I c:\delete.reg
C:\DELETE.REG contains:
::::::::::::::::::::::::::::::
regedit 4
[-HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\EventLog\Application\Time Serv]
