Windows Registry data types

Each entry in the registry is assigned a data type that defines the specific kind of data that the entry can hold. While the registry supports nine different data types, in practical scenarios, you are likely to encounter only a few specific types while managing registry entries. There are several data types in the Windows Registry, including the following:

• REG_SZ: A string value that can contain a maximum of 4,096 characters
• REG_MULTI_SZ: A string value that can contain multiple strings separated by null characters
• REG_EXPAND_SZ: A string value that can contain variables that are expanded when the value is retrieved
• REG_DWORD: A 32-bit integer value that can be represented in decimal or hexadecimal format
• REG_QWORD: A 64-bit integer value that can be represented in decimal or hexadecimal format
• REG_BINARY: A binary value that can contain any type of data
• REG_LINK: A symbolic link to another registry key
