Detecting the Windows version running on your machine

The following code retrieves the current Windows Operating System name and version (with Service Packs) into a CString.

OSVERSIONINFO osv;
osv.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
CString WindowsPlatform;
if (GetVersionEx(&osv))
{
 // note: szCSDVersion =  service pack  release  
 CString ServiceRelease = osv.szCSDVersion;
 switch(osv.dwPlatformId)
 {
  case VER_PLATFORM_WIN32s: //Win32s on Windows 3.1.
   WindowsPlatform = "Microsoft® Windows 3.1(TM)";
  break;

  case VER_PLATFORM_WIN32_WINDOWS: //WIN32 on 95 or 98
   //determine if Win95 or Win98
   if (osv.dwMinorVersion == 0)
   {
    WindowsPlatform = "Microsoft® Windows 95(TM) " + ServiceRelease;
   }
   else
   {
    WindowsPlatform = "Microsoft® Windows 98(TM) " + ServiceRelease;
   }
  break;

  case VER_PLATFORM_WIN32_NT: //Win32 on Windows NT.
   WindowsPlatform = "Microsoft® Windows NT(TM) "  + ServiceRelease;
  break;

  default:
   AfxMessageBox("Failed to get correct Operating System.", MB_OK);  
 } //end switch
} //end if
