Recent releases have seen the introduction of Windows 7, which is now officially named Windows 7 Home Premium. Like Vista, it is an operating system designed for home and machine use only.
Like its predecessor, Windows 7 has the standard features such as Start Menu and Widows Store to help you get around. It also has some new features like Live Tiles that display updates to your apps and other notifications.
To take advantage of Windows 7 on your computer, you need to upgrade to it from Vista or another later version of Windows. Currently, there is no way to upgrade directly from Xp to 7 on Xp descendants like Linux or Mac OS X.
