Use Request.UserAgent. That will give you what you need. Please not that UserAgent may return a wrong information as browser can allow you to change this.

 if (Request.UserAgent.IndexOf("Windows NT 5.1") > 0)
        {
//xp
        }
        else if (Request.UserAgent.IndexOf("Windows NT 6.0") > 0)
        {
//VISTA
        }
        else if (Request.UserAgent.IndexOf("Windows NT 6.1") > 0)
        {
//7
        }
