If the function succeeds, the return value is a DWORD value that contains the major and minor version numbers of Windows in the low order word, and information about the operating system platform in the high order word.
For all platforms, the low order word contains the version number of Windows. The low-order byte of this word specifies the major version number, in hexadecimal notation. The high-order byte specifies the minor version (revision) number, in hexadecimal notation.
To distinguish between operating system platforms, use the high order bit and the low order byte, as shown in the following table: Platform

Low order byte (major version number)

3
For Windows NT and Win32s, the remaining bits in the high order word specify the build number.
For Windows 95 the remaining bits of the high order word are reserved. |
