Hi All, I have installed Windows 10 in my testing machine. I have checked the Major, Minor and Build version for the Windows 10 Programmatically as shown below. Major: 6 Minor: 2 Build: 9200 (But i got the same result in Windows 8 and 8.1 OS) So, please let me know the correct details(Major, Minor and Build number). Fast response will be much appreciated. Thanks, Kathiresan S.
