Office 2010 will reach its end of support on October 13, 2020. If you haven’t already begun to upgrade your Office 2010 environment, Microsoft recommend you start now.
Also, support for Windows 7 ended on January 14, 2020. Even though Office 2010 is still supported until October, Windows 7 will no longer receive security updates after January 2020, unless you purchase Extended Security Updates (ESU). Without ESU, Windows 7 is vulnerable to security threats. For more information, see the Windows 7 end of support site and Lifecycle FAQ-Extended Security Updates.
