In later chapters, you’ll learn how to use the powerful RegEdt32 application, as well as how to write your own programs that find, store, and modify Registry data. As a departure point, though, let’s start with RegEdit, a simple, easy-to-use tool that will help you get familiar with the mechanics of navigating and editing the Registry.

• It is completely ...
