Windows 7 comes in three editions: Windows 7 Home Premium, Windows 7 Professional and Windows 7 Ultimate. Windows 7 Home Premium is the recommended choice for consumers. It offers a full- function PC experience and a visually rich environment from the way they experience entertainment to the way they connect their devices. Windows 7 Professional is the recommended choice for small businesses and for people who work at home but have to operate in an IT-managed or business environment where security and productivity are critical. Windows Ultimate is recommended for users who need all features available in both Home Premium and Professional in one package.
