The Windows Registry is a hierarchical database that stores low-level settings for the Microsoft Windows operating system and for applications that opt to use the registry. The kernel, device drivers, services, Security Accounts Manager, and user interface can all use the registry. The registry also allows access to counters for profiling system performance. Registry Hives. A hive is a group of keys, subkeys, and values in the registry that has a set of supporting files containing backups of its data. The setup phase of the Windows boot process automatically retrieves data from these supporting files. You can also retrieve data manually using the Import Registry File menu item of the Registry Editor (Regedit.exe). The Windows Registry is a centralized hierarchical database that contains both system and user information and settings for Windows computers. These settings can be anything from a user’s desktop background to the time zone setting for the computer. The manual approach – modifying an existing entry. The windows registry is comprised of 5 major sections referred to as as shown above. Each has a series of of folders (known as ) which in turn have a series of containing specific system/program configuration values.
The Registry contains information used by Windows and your programs. The Registry helps the operating system manage the computer, it helps programs use the computer’s resources, and it provides a location for keeping custom settings you make in both Windows and your programs.
For example, when you change the Windows desktop, the changes are stored in the Registry. When you see a list of recently opened files, that list is stored in the Registry. And, changes you make to the status bar in Word — yep, they’re kept in the Registry, too.
The Registry is essentially a database. Its information is stored on disk for the most part, though dynamic information also exists in the computer’s memory. (That dynamic information concerns the computer’s hardware and operating state.) All the information is organized by using a structure similar to folders in the file storage system.
The top level of the Registry contains hives, each of which starts with the curious word HKEY.
Beneath the hives are folders, or keys. Keys can also have subkeys, just as folders have subfolders. The name of the game is organization.
Keys contain values. Every value has a name and data. Unlike the old ini files, the data can be something other than text, including numeric values and binary information. You can find several values in a single key, or a key can be empty or contain only subkeys.
As with files and folders, values stored in the Registry are found by following a pathname Driver tuner 4.0 serial. that gives the location of a specific key or value. For example, the following pathname to the key gives the location where Adobe Acrobat Reader 8.0 is installed on the computer:
The abbreviation HKCU for HKEY_CURRENT_USER is used in the preceding line. It’s followed by the subkeys Software, Adobe, Acrobat Reader, 8.0, and, finally, InstallPath. In the InstallPath key is a value that holds data in the form of text. The text is the pathname for the storage system location where Acrobat Reader 8.0 is installed.

Keys, like pathnames to files, can get long. Sometimes, a key name that’s too long to fit on a single line must be wrapped, such as
Understanding Windows Registry
This key contains a binary value that determines whether Windows displays a shadow on the mouse pointer. The line is too long to fit on the page, so it wraps.

Incidentally, the CursorShadow key helps demonstrate a point that deserves emphasis: You can easily turn the mouse pointer shadow on or off by using the Pointers tab in the Mouse Properties dialog box. You don’t have to delve into the Registry, nor is there any benefit to doing so.
