Members

ProcessorArchitecture

The system's processor architecture. This member can be one of the following values.

Value	Meaning
PROCESSOR_ARCHITECTURE_AMD64 9	x64 (AMD or Intel)
PROCESSOR_ARCHITECTURE_ARM 5	ARM
PROCESSOR_ARCHITECTURE_IA64 6	Intel Itanium
PROCESSOR_ARCHITECTURE_INTEL 0	x86
PROCESSOR_ARCHITECTURE_UNKNOWN 0xffff	Unknown processor.

ProcessorLevel

The system's architecture-dependent processor level.

If ProcessorArchitecture is PROCESSOR_ARCHITECTURE_INTEL, ProcessorLevel can be one of the following values.

Value	Meaning
3	Intel 80386
4	Intel 80486
5	Intel Pentium
6	Intel Pentium Pro or Pentium II

If ProcessorArchitecture is PROCESSOR_ARCHITECTURE_IA64, ProcessorLevel is set to 1.

ProcessorRevision

The architecture-dependent processor revision.

Processor	Value
Intel 80386 or 80486	A value of the form xxyz. If xx is equal to 0xFF, y - 0xA is the model number, and z is the stepping identifier. For example, an Intel 80486-D0 system returns 0xFFD0. If xx is not equal to 0xFF, xx + 'A' is the stepping letter and yz is the minor stepping.
Intel Pentium, Cyrix, or NextGen 586	A value of the form xxyy, where xx is the model number and yy is the stepping. Display this value of 0x0201 as follows: Model xx, Stepping yy

Processor

Value

Intel 80386 or 80486

A value of the form xxyz.

If xx is equal to 0xFF, y - 0xA is the model number, and z is the stepping identifier. For example, an Intel 80486-D0 system returns 0xFFD0.

If xx is not equal to 0xFF, xx + 'A' is the stepping letter and yz is the minor stepping.

Intel Pentium, Cyrix, or NextGen 586

A value of the form xxyy, where xx is the model number and yy is the stepping. Display this value of 0x0201 as follows:

Model xx, Stepping yy

Reserved0

This member is reserved for future use and must be zero.

NumberOfProcessors

The number of processors in the system.

ProductType

Any additional information about the system. This member can be one of the following values.

Value	Meaning
VER_NT_DOMAIN_CONTROLLER 0x0000002	The system is a domain controller.
VER_NT_SERVER 0x0000003	The system is a server.
VER_NT_WORKSTATION 0x0000001	The system is running Windows XP, Windows Vista, Windows 7, or Windows 8.

MajorVersion

The major version number of the operating system. This member can be 4, 5, or 6.

MinorVersion

The minor version number of the operating system.

BuildNumber

The build number of the operating system.

PlatformId

The operating system platform. This member can be one of the following values.

Value	Meaning
VER_PLATFORM_WIN32s 0	Not supported
VER_PLATFORM_WIN32_WINDOWS 1	Not supported.
VER_PLATFORM_WIN32_NT 2	The operating system platform is Windows.

CSDVersionRva

An RVA (from the beginning of the dump) to a MINIDUMP_STRING that describes the latest Service Pack installed on the system. If no Service Pack has been installed, the string is empty.

Reserved1

This member is reserved for future use.

SuiteMask

The bit flags that identify the product suites available on the system. This member can be a combination of the following values.
