[Windows 7] Mainstream support for 7 ended on January 13, 2015. Extended support will end on January 14, 2020. In January 2016, Microsoft announced that support for operating systems older than Windows 10 will be dropped from devices with Intel «Skylake» processors effective July 17, 2017. After this date, systems running Skylake processors will only receive the «most critical» updates for Windows 7, and only if they have been judged not to effect the reliability of Windows 7 on older hardware. Additionally, Microsoft will only support Windows 10 on all future Intel-compatible CPU microarchitectures (including Intel's Kaby Lake and AMD's Bristol Ridge). Microsoft stated that due to the age of the platform, it would be «challenging» for these newer hardware, firmware, and device driver combinations to properly run under Windows 7, especially for system-on-chip systems. This will not affect the support status of other systems, which will continue to receive security updates until the end of extended support.
