Skylake systems supported on Windows 7 and Windows 8.1

Last updated: February 3, 2016

The following is a list of computer manufacturers (OEMs) who have identified over 100 models of systems with Intel’s 6th generation of processors, also known as Skylake, that will be supported on Windows 7 and Windows 8.1. Support will be provided until July 17, 2017 and its recommended that these systems be upgraded to Windows 10 as soon as possible. After July 2017, the most critical Windows 7 and Windows 8.1 security updates will be addressed for these configurations, and will be released if the update does not risk the reliability or compatibility of the Windows 7 and Windows 8.1 platform on other devices. For more information regarding Microsoft’s support lifecycle for Windows, please see the Support Lifecycle FAQ.

For each of the supported systems listed on the OEM pages, the OEM has committed to additional testing, regular validation of Windows Updates, and publishing drivers and firmware for Windows 10 on Windows Update which will help unlock the security and power management benefits of Windows 10 once the systems are upgraded.
