GetVersionExA function (sysinfoapi.h)

#include <windows.h>
#include <stdio.h>

void main()
{
    OSVERSIONINFO osvi = {0};
    BOOL bIsWindowsXPorLater = FALSE;

    ZeroMemory(&osvi, sizeof(OSVERSIONINFO));
    osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);

    GetVersionEx(&osvi);

    bIsWindowsXPorLater =

       ( (osvi.dwMajorVersion == 5) && (osvi.dwMinorVersion >= 1) ));

* For applications that have been manifested for Windows 8.1 or Windows 10. Applications not manifested for Windows 8.1 or Windows 10 will return the Windows 8 OS version value (6.2). To manifest your applications for Windows 8.1 or Windows 10, refer to Targeting your application for Windows.

In Windows 8.1 and later, the GetVersion and GetVersionEx functions have been deprecated. As of Windows 10, the VerifyVersionInfo function is also deprecated. You can still call the deprecated functions, but if your application doesn't specifically target Windows 8.1 or later, then the functions will return the Windows 8 version (6.2). 

In order for your app to target Windows 8.1 or later, you'll need to include an app (executable) manifest for the app's executable. Then, in the <compatibility> section of the manifest, you'll need to add a <supportedOS> element for each Windows version you want to declare that your app supports.

The following example shows an app manifest file for an app that supports all versions of Windows from Windows Vista to Windows 11:

<!-- example.exe.manifest -->
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv3="urn:schemas-microsoft-com:asm.v3">
