Not entirely. According to the Delphi documentation RootKey needs to be 
set instead of CurrentKey and also the key must be closed in the end. 
I've already done the implementation and I'm currently testing it.
As a workaround for older FPC versions simply set RootKey to the value 
returned by RegConnectRegistry.
Note: The login stuff mentioned on the MSDN page needs to be done 
nevertheless.
