`size`	`uint32`	The structure's size in bytes, `sizeof(OsVersionInfoEx)`, which the caller sets before the call.
`majorVersion`	`uint32`	The major version: 10 for both Windows 10 and Windows 11.
`minorVersion`	`uint32`	The minor version: 0 for both Windows 10 and Windows 11.
`buildNumber`	`uint32`	The build number, such as 26100, which tells the releases apart.
`platformId`	`uint32`	The platform: 2, `VER_PLATFORM_WIN32_NT`, on every supported release.
`csdVersion`	`char16[N]`	The NUL-terminated UTF-16 name of the latest service pack, empty on current releases.
`servicePackMajor`	`uint16`	The major version of the latest service pack.
`servicePackMinor`	`uint16`	The minor version of the latest service pack.
`suiteMask`	`uint16`	The `VER_SUITE_` bits saying which product suites are installed.
`productType`	`uint8`	Whether this is a workstation, `VER_NT_WORKSTATION`, a domain controller or a server.
`reserved`	`uint8`	Reserved.

`VER_NT_WORKSTATION`

pub const VER_NT_WORKSTATION: uint8 = 1;

VER_NT_WORKSTATION: the product type of a desktop edition, as opposed to a server.

`RtlGetVersion`

pub extern func RtlGetVersion(info: *var OsVersionInfoEx) -> int32

Reads the true version of the running system, whatever the program's manifest declares. The caller sets size first; the call fills in every other field, csdVersion and the fields after it included, because the size says the structure is the extended one. It returns an NTSTATUS rather than a Bool, and sets nothing GetLastError reports.

Parameters

Name	Type	Description
`info`	`*var OsVersionInfoEx`	the structure to fill, with `size` set to `sizeof(OsVersionInfoEx)`

Returns: zero, STATUS_SUCCESS, which is the only status the call returns
