Windows 7’s five years of extended support will end on January 14, 2020 that’s precisely one year from today. Microsoft will no longer release free security updates, bug fixes and new functionalities for the operating system that’s still widely used by people. Microsoft stopped the mainstream support for Windows 7 in January 2015, but Windows users have continued to receive security updates and patches for known security issues. As many as 43% of enterprises are still running the nine-year-old operating system, of which 17% didn’t know when Microsoft’s end of support deadline hit.
