For Windows 7 (including Service Pack 1), support ended January 14, 2020, and on January 10, 2023 for Windows 8.1; this will cause the same "unfixed vulnerabilities" issue for users of these operating systems. Support for Windows 8 already ended January 12, 2016 (with users having to install Windows 8.1 or Windows 10 to continue to get support), and support for Windows 7 without SP1 was ended April 9, 2013 (with the ability to install SP1 to continue to get support until 2020, or having to install Windows 8.1 or Windows 10 to receive support after 2020).
