Microsoft says it doesn’t plan to provide security updates for the Microsoft Security Essentials component integrated into Windows 7 after the operating system reaches its end of life in a little over five weeks.
The life of Windows 7 is set to end on January 14th, 2020, and security updates for the operating system will cease to arrive. Microsoft Security Essentials is the antivirus component implemented by default on Windows 7, but that tool will be abandoned along with everything else.
