The registry, often known as the Windows registry, is a database containing information, settings, choices, and other variables for software and devices installed on all versions of Microsoft Windows.
The registry can be accessed by the kernel, device drivers, services, Security Accounts Manager, and user interfaces. The registry also provides access to counters that may be used to profile system performance.
In other words, the registry, also known as the Windows Registry, stores information, settings, choices, and other data for applications and devices installed on all versions of Microsoft Windows. When software is installed, for example, a new subkey containing settings such as a program's location, version, and how to start the application is added to the Windows Registry.
When you initially use the Windows Registry Editor, it shows all registry values in root keys. What do they mean? What do they imply? This section provides a quick overview of the most frequent root keys and the values they contain.
▶ Root key
• HKCR (HKEY_CLASSES_ROOT): It describes file type, file extension, and OLE information.
• HKCU (HKEY_CURRENT_USER): It contains information about the individual who is presently signed in to Windows as well as their settings.
• HKLM (HKEY_LOCAL_MACHINE): It contains computer-specific information such as installed hardware, program settings, and other data. The data is utilized by all users that access the machine. This key and its subkeys are among the most frequently accessed and modified regions of the registry by users.
• HKU (HKEY_USERS): In includes information about all the users who log on to the computer, including both generic and user-specific information.
• HKEY_CURRENT_CONFIG (HKCC): The details about the current configuration of hardware attached to the computer.

• REG_MULTI_SZ -- String array value: All multi-line string values.
• REG_EXPAND_SZ -- Expanded string value: It contains a string with environmental or system variables that need to be expanded. For example, c:\%windir%\example.exe could be the same as C:\windows\example.exe.
• REG_BINARY -- Binary value: Allows for attributes to be defined in binary as either on or off (0 or 1).
• REG_DWORD -- DWORD value: Similar to the binary value, but capable of values being defined in either 32-bit decimal or hex.
• REG_QWORD -- QWORD value: Like the DWORD, but stored as a 64-bit value.
