followed by the release of three pre-release versions from September 2011
to May 2012. The operating system was released to manufacturing on
August 1, 2012, and was released for general availability on October 26,
2012.[7]
Windows 7 is a personal computer operating system developed
by Microsoft, a version ofWindows NT. Development of Windows 7
occurred as early as 2006 under the codename "Blackcomb." Windows
7 was released to manufacturing on July 22, 2009,[8] and became
generally available on October 22, 2009,[9] less than three years after

24.  Microsoft seemed to hit full stride with
Windows 7, developing a fast and
efficient operating system. Thankfully
it seems Windows 8 continues to
build on that pattern as we found it to
be on par with and occasionally faster
than Windows 7.
 The improvements that have been
made to startup and shutdown times
are self-evident, and no doubt a major
focus on the new OS’ development.
