System registry is always seen as both a location for experts to do magnificent operations and as a source of trouble as well. You can virtually tune every aspect of every possible software piece on your system from system registry even those aspects that are not exposed using any user interface at all. This is all in addition to the thousands (not hundreds!) of other operations that are even not tuning and are much ahead the already complex tuning. If you can access registry from your applications then you freely and automatically can give your application the capabilities to benefit from this magnificent world.
