Windows 7 (formerly codenamed Blackcomb and Vienna) is the next release of Microsoft Windows, an operating system produced by Microsoft for use on personal computers, including home and business desktops, laptops, Tablet PCs, and media center.
Microsoft stated in 2007 that it is planning Windows 7 development for a three-year time frame starting after the release of its predecessor,
Windows Vista, but that the final release date will be determined by product quality.
Unlike its predecessor, Windows 7 is intended to be an incremental upgrade with the goal of being fully compatible with existing device drivers, applications, and hardware. Presentations given by the company in 2008 have focused on multi-touch support, a redesigned Windows Shell with a new
taskbar, a home networking system called HomeGroup, and performance improvements. Some applications that have been included with prior releases of Microsoft Windows, most notably Windows Mail, Windows Calendar,[citation needed] Windows Movie Maker, and Windows Photo Gallery, are no longer included with the operating system; they are instead offered separately (free of charge) as part of the Windows Live Essentials suite.source: www.wikipedia.orgfurther information about windows 7 click here.
