There are two ways of working with the registry; software based and direct access. The software based method is generally considered to be safe, although a badly behaved piece of software that mangles the registry can make you doubt the wisdom of this statement. Anyone who has used a computer is familiar with the software based method of making changes. Control Panel is an excellent example. Make a change to one of the Control Panel settings and almost assuredly you have initiated a change within the registry. It's just that you are insulated by Control Panel from seeing what went on behind the scenes in the registry.
