KEY_VALUE_BASIC_INFORMATION defines a subset of the full information available for a value entry of a registry key.

Members

TitleIndex
Device and intermediate drivers should ignore this member.
Type
The system-defined type for the registry value in the Data member, which is one of the following:

REG_XXX Type

Value

REG_BINARY

Binary data in any form

REG_DWORD

A 4-byte numerical value

REG_DWORD_LITTLE_ENDIAN

A 4-byte numerical value whose least significant byte is at the lowest address

REG_DWORD_BIG_ENDIAN

A 4-byte numerical value whose least significant byte is at the highest address

REG_EXPAND_SZ

A zero-terminated Unicode string, containing unexpanded references to environment variables, such as “%PATH%”

REG_LINK

A Unicode string naming a symbolic link. This type is irrelevant to device and intermediate drivers

REG_MULTI_SZ

An array of zero-terminated strings, terminated by another zero

REG_NONE

Data with no particular type

REG_SZ

A zero-terminated Unicode string

REG_RESOURCE_LIST

A device driver’s list of hardware resources, used by the driver or one of the physical devices it controls, in the \ResourceMap tree

REG_RESOURCE
_REQUIREMENTS_LIST

A device driver’s list of possible hardware resources it or one of the physical devices it controls can use, from which the system writes a subset into the \ResourceMap tree

REG_FULL_RESOURCE
_DESCRIPTOR

A list of hardware resources that a physical device is using, detected and written into the \HardwareDescription tree by the system

NameLength
