Security and feature updates will no longer be available
You can continue to use Windows 7, but once support ends, your PC will become more vulnerable to security risks. Windows will operate but you will stop receiving security updates.
Windows 7 can still be installed and activated after support has ended. However, to avoid unnecessary security risks and viruses, Microsoft strongly recommends that you use Windows 10 instead.
Support for Internet Explorer on Windows 7 devices will be discontinued on January 14, 2020. As a component of Windows operating system, Internet Explorer follows the same support lifecycle.
