Windows 7 Operating System Version

As i was building a new desktop application for Windows7, I was adding support to detect if user's operating system was Windows 7 or not. So I fired up handy Win32 API GetVersionEx. I don't know for some reason I was hoping to see a major version number revision to 7 for Windows 7 release. Well, it was not. There is only a minor version number increment to 1 from 0 that was used for Vista. So you will see that for Windows 7, major version number is still 6. You can see it from the debugger screen shot of my little application.

I guess this falls in line with what most people have been saying that Windows 7 is not a major change in windows operating system but it is a better version of Windows Vista. I guess after looking at these numbers of dwMajorVersion and dwMinorVersion, MS has also indicating that Windows 7 is not a major release for operating system.
