Windows 7: A Major Release of the Windows NT Operating System

Until April 9, 2013, Windows 7 was included in updates and technical support. After this date, users had to install Service Pack 1 to receive support and updates. This operating system is still used on personal computers, including home and business desktops, laptops, tablet PCs, and media center PCs.

Released on July 22, 2009, Windows 7 was a major release of the Windows NT operating system developed by Microsoft. It replaced Windows Vista, which was released nearly three years earlier. The operating system became generally available on October 22, 2009.

Installing Service Pack 1 is necessary for users to receive updates and support after April 9, 2013. There are some exceptions, so it's important to check the support lifecycle for more information. Security updates were available until January 10, 2023, excluding some embedded editions.

Windows 7 was eligible for Extended Security Updates (ESU) service, which provided continued security and support through yearly installments. However, mainstream support ended on January 13, 2015, while extended support ended on January 14, 2020.

Overall, Windows 7 was a major release of the Windows NT operating system, offering many improvements over its predecessor, Windows Vista.
