Windows 7

Windows 7 is a graphical interface operating system developed by Microsoft for use on personal computers, including desktops, tablet PCs, laptops and netbooks. It was released on July 22 of 2009 in manufacturing companies and released to the general retailers on October 22, 2009. It serves as a successor to Windows Vista, which was released 3 years before 2009. Windows Server 2008 R2 was released around the same time as Windows 7.

Unlike its predecessor Windows Vista, which introduced a large number of new features, Windows 7 was primarily intended to be a more focused, incremental to the Windows line of operating systems, with the primary goal of having software and applications that were already compatible with Windows Vista. Some standard applications that have been included in previous Windows installments, like Windows Calendar, Windows Mail, Windows Movie Maker and Windows Photo Gallery are now offered separately at no charge as part of the Windows Essentials suite of software.

New Features
Windows 7 includes a multitude of new features, like the advances in touch and handwriting recognition, support for virtual hard disks, improved performance on multi-core processors, improved boot performance, DirectAccess and kernel improvements.
