SAN FRANCISCO, Oct. 22 (Xinhua) -- Microsoft Corp. began to roll out Windows 7 operating system on Thursday with the hope of shaking off the negative image created by previous Vista version and maintain its dominance on the global market of personal computer (PC) operating systems.
SEATTLE, Oct. 23, 2009 After the troublesome release of Windows Vista, Microsoft is taking a chance on the newest form of its operating system, Windows 7.
The upgrade program, which let someone buy a PC with Windows Vista and later install Windows 7 on it for free, meant that Microsoft counted only half of its Windows sales in the period.
