New and Changed Features[change | change source]

Windows 7 includes many new features, such as touching the screen, supporting virtual hard disks, being faster on multi-core processors, and a redesigned taskbar. The taskbar allows users to pin the most frequently used programs directly to it, instead of on a toolbar. The glass user interface, Aero, has been improved with features such as Aero Shake, Aero Snap, and Aero Peek.

Windows 7 has removed some features that were in Windows Vista, including Windows Mail, Windows Movie Maker, Windows Photo Gallery, Windows Calendar, Windows Ultimate Extras, and the InkBall game, as well as many customization options such as the Classic Start Menu. Windows Mail, Windows Movie Maker, and Windows Photo Gallery were replaced by similar set of programs known as Windows Live Essentials. The Windows Live Essentials are not included in Windows 7, and have to be downloaded from Microsoft's website.

Editions[change | change source]

There are six editions of Windows 7, which contain different features that are meant to be suited for the customer:

  • Starter (for low-cost Personal computers)
  • Home Basic (released only in poor countries)
  • Home Premium (for home users)
  • Professional (for small businesses)
  • Ultimate (all features)
  • Enterprise (same as Ultimate, but for businesses)

Development[change | change source]

At first, a major version of Windows code-named Blackcomb was planned as the successor to Windows XP and Windows Server 2003. Features planned for Black-comb included the Sidebar, an emphasis on looking for data, and an advanced storage system named WinFS. However, a minor release code-named Longhorn was announced for 2003, delaying the making of Blackcomb.[6] By the middle of 2003, Longhorn had gotten some of the features meant for Blackcomb. After three major viruses exploited flaws in Windows operating systems within a short time in 2003, Microsoft changed its development priorities, putting some of Longhorn's major development work on hold while they made new service packs for Windows XP and Windows Server 2003. Development of Longhorn was reset in September 2004, and it was renamed to Windows Vista. A number of features were cut from Windows Vista as it was being remade.[7]

After Windows Vista was released, Microsoft announced a new plan for the next version of Windows, code-named Windows 7, in 2007.[8] In 2008, it was announced that Windows 7 would also be the official name of the operating system.[9][10]
