One of the things about Windows which a great deal of users have come to love is also one of the things which a lot of people have taken the opportunity to have a dig at the Redmond company for. There's no doubt that Windows has been the most popular desktop operating system over the years, with millions of people across the world loving the fact that Microsoft has introduced new versions of the OS while rigidly sticking to a tried, tested and familiar visual user-experience. By that I mean it doesn't matter if you pick up Windows 98, XP, Millennium, Vista or 7, you automatically know from experience where things are and can get up and running right away.
