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 Movie Maker and Windows Photo Gallery, are no longer included with the operating system; they are instead offered separately as part of the Windows Live Essentials suite.
