Back in January, Microsoft shared they would cut off extended support for Windows 7 and 8.1 on 6th Gen Intel Core (Skylake) begining of July 2017.
Then in the March of this year, the company modified the extended support cut-off date to July 17, 2018, with [all "critical" updates would be supported through 2020 for Windows 7 and 2023 for 8.1].
Enterprise customers are moving to Windows 10 faster than any version of Windows. At the same time, we recognize that, in some instances, customers have a few systems that require longer deployment timeframes.
We listened to this feedback and today are sharing an update to our 6th Gen Intel Core (Skylake) support policy.*
Today, 5 months later, the Redmond broadened the support period further "from July 17, 2018 to the end of support dates for Windows 7 and Windows 8.1."
With todays's policy change, the extended support for Windows 7 now ends on January 14, 2020. And, for Windows 8.1, the support extends upto January 10, 2023.
For those unfamiliar, "extended support means the period during which users will get regular security updates from Microsoft for free."
The company further said that "they will provide all applicable security updates throught out the period."
Microsoft is going to support 6th Gen Intel Core devices on Windows 7 and Windows 8.1 with all applicable security updates until the end of support for Windows 7 and Windows 8.1.
However, customers who are on 6th Gen Intel Core systems on Windows 7 and Windows 8.1, are advised to upgrade as soon as possible to be able to receive full support along with the enhancements that come from running modern hardware with modern software.
Microsoft adds that "this policy change primarily applies to our commercial customers who are currently managing deployments with Windows 7 and Windows 8.1."
Customer who are running on Windows 10 are not covered under this policy change.
"This change is designed to help our customers purchase modern hardware with confidence, while continuing to manage their migrations to Windows 10," the company stated.
For Windows 10, Microsoft reporting that there are over 350 million devices now running on Windows 10, with more than 135 billion hours of use since the launch.
Adding, it noted, enterprise customers are deploying Windows 10 to devices every day.
This change is made possible through the strong partnership with our OEM partners and Intel who will be performing security update validation testing and upgrade testing for 6th Gen Intel Core systems running Windows 7 and Windows 8.1 through the end of support dates.
As communicated earlier this year, today's support cut-off changes do not affect "future silicon platforms including Intel's upcoming 7th Gen Intel Core (Kaby Lake) processor family and AMD's 7th generation processors (e.g. Bristol Ridge)." Those hardware as previously announced will only be supported on Windows 10, and "all future silicon releases will require the latest release of Windows 10," added Microsoft.
