Note: In the official msdn documentation, the description → OSVersion attribute reports two identical versions (6.2.0.0) Windows 8 and Windows 8.1. In some cases, the OSVersion attribute may not return the OS version that matches the version of the specified Windows program compatibility mode feature.

Code:

    public class GetOSystem    {        private const string Windows2000 = "5.0";        private const string WindowsXP = "5.1";        private const string Windows2003 = "5.2";        private const string Windows2008 = "6.0";        private const string Windows7 = "6.1";        private const string Windows8OrWindows81 = "6.2";        private const string Windows10 = "10.0";        private string OSystemName;        public void setOSystemName(string oSystemName)        {            this.OSystemName = oSystemName;        }        public  GetOSystem()        {            switch (System.Environment.OSVersion.Version.Major + "." + System.Environment.OSVersion.Version.Minor)            {                case Windows2000:                    setOSystemName("Windows2000");                    break;                case WindowsXP:                    setOSystemName("WindowsXP");                    break;                case Windows2003:                    setOSystemName("Windows2003");                    break;                case Windows2008:                    setOSystemName("Windows2008");                    break;                case Windows7:                    setOSystemName("Windows7");                    break;                case Windows8OrWindows81:                    setOSystemName("Windows8.OrWindows8.1");                    break;                case Windows10:                    setOSystemName("Windows10");                    break;            }            Console.WriteLine(OSystemName);        }    }
