Return a named tuple describing the Windows version
currently running. The named elements are *major*, *minor*,
*build*, *platform*, *service_pack*, *service_pack_minor*,
*service_pack_major*, *suite_mask*, and *product_type*.
*service_pack* contains a string while all other values are
*service_pack_major*, *suite_mask*, *product_type* and
*platform_version*. *service_pack* contains a string,
*platform_version* a 3-tuple and all other values are
integers. The components can also be accessed by name, so
``sys.getwindowsversion()[0]`` is equivalent to
``sys.getwindowsversion().major``. For compatibility with prior
versions, only the first 5 elements are retrievable by indexing.
*platform* may be one of the following values:
+-----------------------------------------+-------------------------+
| Constant | Platform |

This function wraps the Win32 :c:func:`GetVersionEx` function; see the
Microsoft documentation on :c:func:`OSVERSIONINFOEX` for more information
about these fields.
*platform_version* returns the accurate major version, minor version and
build number of the current operating system, rather than the version that
is being emulated for the process. It is intended for use in logging rather
than for feature detection.
