Microsoft has been urging customers to upgrade from its Windows 7 operating system, while attempting to ease the transition with several options for extended support. It will stop providing routine fixes and security patches effective January 2020. Regular support for Windows Server 2008 also is scheduled to end at that time. Windows 7 enterprise customers can subscribe to Extended Security Updates to receive security fixes for uncovered or reported vulnerabilities in the OS — those rated "Critical" or "Important" by Microsoft.
