Its All New Windows 7
Windows 7 (formerly codenamed Blackcomb and Vienna) will be the next version of Microsoft Windows, an operating system produced by Microsoft Corporation for use on personal computers, including home and business desktops, laptops, tablet PCs, netbooks and media center PCs. Representatives of Microsoft estimated in 2007 that Windows 7 would have a three-year development time frame following the release of its predecessor Windows Vista, but that the release date would ultimately be determined by product quality.
Unlike its predecessor, Windows 7 is intended to be an incremental upgrade to the Windows line, with the goal of being compatible with applications and hardware with which Windows Vista is already compatible. 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 Movie Maker and Windows Photo Gallery, will not be included in Windows 7, but will instead be offered separately as part of the freeware Windows Live Essentials suite.
