Windows registry is a database which has a hierarchal structure, like the directories on your hard disk. The registry contains two basic elements: keys and values. Keys are similar to folder, as folder contains further sub folders. Each key can contain other sub key which in turn contains other sub key, as well as values. Each value contains the actual information stored in the registry. Keys are referenced by backslashes to indicate level of hierarchy.
For example-HKEY_LOCAL_MACHINE\Software\Microsoft\Windows refers to the sub key "Windows" of the sub key "Microsoft" of the sub key "Software" of the HKEY_LOCAL_MACHINE key.
The registry is divided in to number of logical sections or hives .Hive names begin with HKEY. There are five main branches, and each contains specific information stored in the registry
1.HKEY_CLASSES_ROOT: This branch stores information about registered application, file types as well as OLE information for all OLE-aware applications.
2.HKEY_CURRENT_USER: This branch stores settings that are specific to the user currently logged in.
3.HKEY_LOCAL_MACHINE: It stores settings that are general to all the users of the system, i.e. all of the hardware and software installed on your computer. Since multiple hardware configuration can be specify, the current hardware configuration is specified in HKEY_CURRENT_CONFIG.
4.HKEY_USERS: This branch contains certain preferences such as colors and control panel settings for each of the users on the computer.
5.HKEY_CURRENT_CONFIG: It contains information gathered at runtime; information stored in this key is not permanently stored on disk, but rather regenerated at boot time. It points to the part of HKEY_LOCAL_MACHINE appropriate for the current hardware configuration.
