Windows 7 Release Date Windows 7 was released to manufacturing on July 22, 2009. It was made available to the public on October 22, 2009. It's preceded by Windows Vista, and succeeded by Windows 8. Windows 11 is the latest version of Windows, released in 2021. Windows 7 Support The Windows 7 end-of-life was on January 14, 2020. This was when Microsoft discontinued technical support and quit supplying Windows 7 users with software updates and security fixes through Windows Update. On January 14, 2020, Microsoft also ended support for the following for Windows 7 users: Internet ExplorerGames like Internet Checkers and Internet BackgammonMicrosoft Security Essentials platform (signature updates remain) Although Windows 7 has been discontinued, it can still be activated and installed on new computers. If you're a Microsoft 365 user, Microsoft continued to provide security updates for Microsoft 365 through January 2023, but not feature updates. I recommend installing Windows 11 or upgrading to Windows 10 to continue receiving security updates and technical support.
