REG_LINK: a symbolic link between system or application data and a registry value.

(Opposite of the order of REG_DWORD and REG_DWORD_LITTLE_ENDIAN.)

REG_DWORD_BIG_ENDIAN: a 32-bit number with the most significant byte is the rightmost, or low-order, byte.

REG_DWORD_LITTLE_ENDIAN: same as REG_DWORD.

The values stored under keys are either the default, "value not set," or one of the following data types (note that only the first five values were used in Windows versions before Windows 2000):

HKEY_CURRENT_CONFIG: information about the current hardware profile.

HKEY_LOCAL_MACHINE: system-related information.

HKEY_CLASSES_ROOT: file association and Object Linking and Embedding registration information.

HKEY_USERS: information about all the accounts on the machine.

HKEY_CURRENT_USER: data associated with the currently logged-on user.

The root keys divide the registry data into categories - note that you can't add new root keys or delete existing ones. Such is the magic of Microsoft development. But they also are called hives, which is not reasonable and merely adds gratuitous obfuscation for no apparent reason. Root key is an understandable concept but these entities also are called root handles, which is reasonable because they are, indeed, handles. There is an extremely geeky reason for this: The root key names are Win32 (that's Windows 32-bit) handles (that's the "H" part) to keys ("KEY"). You will note that all root key names start with HKEY.

Finally, values have names (any characters other than "\", "*" or "?"), types (which we'll get to in a second) and data. Subkeys also can contain further subkeys and values. Under the root of registry hierarchy - called My Computer - are root keys that are like subdirectories and they can contain subkeys (sub-subdirectories) and values. Anyway, let's talk about how the registry is organized, and in doing so we'll focus on Windows XP and 2000.Īt its heart, the Windows registry is a hierarchical database. Just treat it with the respect it deserves. But let's get real: Messing with the registry is as dangerous as messing with the file system. Microsoft has turned the registry into a mysterious object that it says is best left to uber-geeks. Your system might not start, only partially start or be unstable in one of those "I know something is wrong with this computer but I'm damned if I know what it is" kind of ways. On the other hand, the registry is fragile, and if it should get damaged you could be in for a miserable time.

So is life better? Arguably it is because you can back up the registry and be pretty certain that most of your key settings are safe. Note that not all applications store all of their settings in the registry - some applications ignore it! So now we have the registry (a nightmare in and of itself) as well as configuration files.
