About the Windows Registry
The Windows registry is a system-wide database that contains configuration information used by applications and
the operating system. The registry stores all kinds of information, including the following:
•
Application information such as company name, product name, and version number
•
Path information that enables your application to run
•
Uninstallation information that enables end users to uninstall the application easily without interfering with
other applications on the system
•
System-wide file associations for documents created by an application
•
License information
•
Default settings for application options such as window positions
Keys, Value Names, and Values
The registry consists of a set of keys arranged hierarchically under the My Computer explorer. Just under My
Computer are several root keys. An installation can add keys and values to any root key of the registry. The root
keys that are typically affected by installations are:
•
HKEY_LOCAL_MACHINE
•
HKEY_USERS
•
HKEY_CURRENT_USER
•
HKEY_CLASSES_ROOT
A key is a named location in the registry. A key can contain a subkey, a value name and value pair, and a default
(unnamed) value. A value name and value pair is a two-part data structure under a key. The value name identifies a
value for storage under a key, and the value is the actual data associated with a value name. When a value name is
unspecified for a value, that value is the default value for that key. Each key can have only one default (unnamed)
value.
Note that the terms key and subkey are relative. In the registry, a key that is below another key can be referred to as
a subkey or as a key, depending on how you want to refer to it relative to another key in the registry hierarchy.
