Microsoft keeps upgrading their systems to different versions. For instance, Windows systems have seen the progressive transition from windows XP, windows 7, windows 8, 8.1 and the latest Windows 10. It is possible to conclude that upgrade in software matches with increased users since the number of features keep on rising but it is not the case.
