Microsoft Windows 7

Windows 7 (formerly codenamed Blackcomb, then Vienna) is a future version of Microsoft Windows. It is expected to be the successor to Windows Vista. Microsoft has confirmed that the planned development time frame is at least three years, putting the release date around 2010[1]. On July 20, 2007, Microsoft confirmed that Windows 7 is "the internal name for the next version of the Windows Client OS".[1]
Microsoft has refrained from discussing the details about Windows 7 publicly as they focus on the release and marketing of Windows Vista,[2] though some early details of various core operating system features have emerged at developer conferences such as Windows Hardware Engineering Conference in 2006
